feat(release): publish releases directly, and fix the install path in the notes

Releases were created as drafts for one stated reason: nobody had run the
plugin in the OBS GUI on any platform, so a human had to look before anything
became visible. The first confirmed GUI load (Windows, OBS 32.2.2 on Windows
11, 2026-09-09) retired that gate, so `publish-release.sh` now posts
`"draft": False` and the workflow no longer needs a human click.

The caveats did not go away, they moved: the generated release notes now lead
with what is actually confirmed (module loads and registers its source type,
Windows only) and what is not (video rendering, A/V sync, latency, mid-show
publisher restart, Linux and macOS in the GUI at all), and the per-platform
table carries the rest.

Also fixes the third and last copy of the wrong Windows install path. The
release notes template told every downloader to extract into
`%APPDATA%\obs-studio\plugins\`, which on Windows is OBS's config directory
and is never scanned for plugins -- that is what stopped a director's
correctly-shaped install from loading. The notes now carry a per-platform
table (`C:\ProgramData\obs-studio\plugins\` on Windows), the exact finished
path, a warning about Explorer's "Extract All..." wrapper folder, and how to
confirm the load in the OBS log. Both failure modes are silent, which is
precisely why they belong in the notes.

Note the tradeoff now that nothing is held back: assets upload after the
release row is created, so a release is briefly visible with no files
attached. Called out in the script header.

Verified by rendering the heredoc with a stub tag: backslash escaping survives
into correct markdown, and the YAML parses.

 # streamer-tools Camera Plugin -- ${TAG}
 
 Built from commit \`${SHA}\`.
 
-**Nobody has yet run this plugin in the OBS GUI, on any platform.** See "What
-is verified, and how" in \`README.md\` for exactly what has and has not been
-checked, including which claims are backed by automated tests versus a human
-watching OBS.
+**Read the per-platform notes below before relying on this.** The module has
+been loaded in the OBS GUI exactly once -- Windows, OBS 32.2.2 on Windows 11,
+2026-09-09 -- and only "it loads and registers its source type" is confirmed
+there. Whether video renders correctly, A/V sync, end-to-end latency and
+mid-show publisher restart are all still unverified on every platform. See
+"What is verified, and how" in \`README.md\` for exactly what is backed by

 ## Installing
 
-### Linux
+Extract the archive into your OBS plugins folder. **The directory is not the
+same shape on every platform, and picking the wrong one fails silently -- OBS
+logs nothing at all for a plugin it never finds:**
+
+| Platform | Extract into |
+|---|---|
+| Windows | \`C:\\ProgramData\\obs-studio\\plugins\\\` -- **not** \`%APPDATA%\\obs-studio\\\`, which is where OBS keeps its config and is never scanned for plugins |
+| macOS | \`~/Library/Application Support/obs-studio/plugins/\` |
+| Linux | \`~/.config/obs-studio/plugins/\` |
+
+Each archive's top-level folder already matches the shape OBS expects, so
+extracting is the whole install step -- but check the result is exactly one
+folder deep. Windows Explorer's "Extract All..." adds a folder named after the
+zip unless you clear it from the destination box, which nests it one level too
+far and is equally silent. On Windows the finished path must be:
 
 \`\`\`
-mkdir -p ~/.config/obs-studio/plugins/streamer-tools-camera
-unzip streamer-tools-camera-${TAG}-linux-x64.zip -d /tmp/stplugin-camera
-cp -r /tmp/stplugin-camera/bin /tmp/stplugin-camera/data \\
-      ~/.config/obs-studio/plugins/streamer-tools-camera/
+C:\\ProgramData\\obs-studio\\plugins\\streamer-tools-camera\\bin\\64bit\\streamer-tools-camera.dll
 \`\`\`
 
-Start OBS, then Sources -> \`+\` -> "streamer-tools Camera" -> fill in the
-server URL, room slug and read key from the room's settings page ->
-"Refresh camera list" -> pick a camera. This is the same drop-in layout
-README's "Testing this by hand" documents for a source build, adapted for a
-downloaded zip -- known-good on Linux.
-
-### Windows (installation path not yet verified in real OBS)
-
-Per \`AddExtraModulePaths()\` in obs-studio's \`UI/window-basic-main.cpp\`, OBS
-on Windows searches a plugins directory for \`bin\\64bit\\<name>.dll\` plus a
-sibling \`data\\\`. Unzip the archive and copy its \`bin\\\` and \`data\\\` into
-your OBS plugins directory (typically
-\`%APPDATA%\\obs-studio\\plugins\\streamer-tools-camera\\\`), matching the
-Linux layout above. This has not been confirmed against a real OBS install on
-Windows -- report back if you try it.
-
-### macOS (installation path not yet verified in real OBS; packaging gap)
-
-OBS on macOS loads plugins as \`<name>.plugin\` bundles under
-\`~/Library/Application Support/obs-studio/plugins/\`. As of this release,
-this project's \`build/package/\` output on macOS is **not yet that bundle
-shape** -- see the "macOS packaging gap" section of \`README.md\`. Treat the
-macOS archive here as a build-verification artifact, not a working
-drop-in, until that gap is closed.
+To confirm it loaded, restart OBS and check Help -> Log Files -> View Current
+Log for \`streamer-tools-camera\` under "Loaded Modules". Then in OBS: Sources -> \`+\` ->
+"streamer-tools Camera" -> fill in the server URL, room slug and read key
+from the room's settings page -> "Refresh camera list" -> pick a camera.

-**Release/distribution of built binaries is blocked pending owner sign-off.**
-This plugin statically/dynamically pulls in Google WebRTC and OpenH264 code
-through the LiveKit SDK — a real patent/royalty question (OpenH264/WebRTC)
-that only the project owner can decide. Nothing in this repo should be built
-into a package and handed out, posted, or attached to a public release until
-that sign-off happens. See `third_party/livekit/README.md` for the specifics
-of what is and is not currently known/shipped on the licensing side. (CI in
-`.gitea/workflows/build.yml` only builds, tests, and uploads CI-internal

-`.gitea/workflows/release.yml` is the mechanism that *would* publish a
-release, but it does not run automatically: it is gated on someone pushing a
-`v*` tag, which is the actual sign-off gate in practice — don't push one
-until the owner has actually signed off on C1. When it does run, it packages
-each platform's `build/package/` (or macOS's bundle output, once that lands)
-into a zip and creates a **draft** Gitea Release, whose generated release
-notes lead with the same C1 reminder as this section, so whoever opens the
-draft to publish it sees the open question again before doing so. Building
-that mechanism is not the same as clearing C1 — it still requires the same
-owner sign-off before a tag gets pushed.)
-
-The separate license-compatibility question — this repository's own top-level
-`LICENSE` was GPLv2 while the vendored LiveKit binaries are Apache-2.0, which
-are incompatible — is **resolved**: the project owner has relicensed this
-project's own first-party code to Apache-2.0, matching LiveKit. Everything in

+### Windows runner: persistent build tools (2026-09-07)
+
+`winvm-builder`'s Windows job used to install its own CMake + Ninja on every
+single run via `uses: lukka/get-cmake@latest`. That action has its own
+caching (routed through this act_runner's built-in cache server, the same
+mechanism `.deps/`'s `actions/cache` step above relies on and that one does
+work) but it never hit: every run logged `Cloud cache miss` against the same
+cache key, even immediately after a run that logged a successful save under
+that exact key -- some incompatibility between `lukka/get-cmake`'s bundled
+cache client and this act_runner's cache-server implementation, not
+"caching isn't configured." Separately, and the larger cost: the archive
+extraction step alone measured **~7.5 minutes** for a 45MB zip on this VM
+(13:11:14 to 13:18:48 in one captured run) -- consistent with Windows
+Defender real-time-scanning every extracted file, not raw disk I/O, though
+that specific cause is not confirmed. Together this was the dominant cost of
+every Windows CI run, cold cache or not.
+
+Fix: CMake 4.4.2 and Ninja 1.12.1 are now installed once, directly on the
+`winvm-builder` VM (Proxmox VMID 110, host pve4/192.168.1.145), not fetched
+per-run:
+
+- `C:\BuildTools\cmake\` (from
+  `cmake-4.4.2-windows-x86_64.zip`, Kitware's GitHub releases) and
+  `C:\BuildTools\ninja\` (from `ninja-win.zip`, `ninja-build/ninja` v1.12.1
+  release) — plain `Expand-Archive` drops, nothing installed via an
+  installer/MSI.
+- Both added to the **Machine**-level `PATH`
+  (`[Environment]::SetEnvironmentVariable('PATH', ..., 'Machine')`, not
+  `setx`, which silently truncates a `PATH` this long).
+- The `GiteaRunner-winvm-builder` scheduled task (`C:\gitea-runner\
+  gitea-runner.exe daemon`, runs as SYSTEM) was stopped and restarted after
+  the `PATH` change — a already-running process does not pick up an updated
+  Machine environment variable, only processes started after the change do,
+  and every CI job is a child process of this one long-running daemon.
+
+Both workflows' Windows jobs now just run `cmake --version` / `ninja
+--version` as a "Verify build dependencies" step and fail loudly if either
+is missing, instead of silently falling back to the slow per-run install.
+
+**This is VM state, not something `git clone` reproduces.** If
+`winvm-builder` is ever rebuilt or reimaged, redo the three steps above
+(download+extract both zips under `C:\BuildTools\`, extend the Machine

-  `share/livekit/build-info.json`. No licence file of any kind.
-- The repository at tag `v1.10.1` has `LICENSE` (Apache-2.0, 10142 bytes) and
-  `NOTICE` (553 bytes) at its root. There is no `LICENSE.md`, no `NOTICE.md`,
-  and no `THIRD_PARTY_LICENSES` file.

-So what ships here is the Apache-2.0 licence and notice, which is what
-actually exists upstream. **The aggregated third-party notice the design doc
-expected — covering the WebRTC/OpenH264/etc. code statically linked inside
-`liblivekit_ffi.so` — has not been located and is not being shipped.** That
-is a real, open licensing question for whoever signs off on distributing
-release binaries, not something this packaging step has resolved. Worth
-raising upstream, or asking counsel whether the Apache-2.0 NOTICE alone
-suffices for a binary redistribution of that library.
