Visiting a server's own hostname (or its IP, or any unrouted name) on 80/443
could show the Coraza WAF block page. `use_backend default-backend` does not
short-circuit http-request rules, so the catch-all was WAF-inspected with the
full server-wide rule set like customer traffic; a browser on the server
hostname also carries the control panel's cookies (not port-scoped).
Unrouted requests are now answered by HAProxy itself with a tiny static page
(errors/default-splash.html via `http-request return ... file`; 200 on "/",
404 elsewhere) placed before the SPOE call. "Routed" comes from
routed_hosts.list / routed_wildcards.list, written by generate_config() from
the same rows as the routing ACLs, port-stripped + lowercased (superset of the
raw-Host routing ACLs), and part of the rollback set. ACME http-01, blocked
IPs and suspended hosts keep their existing handling; rate limits and gates
still run first. HAPROXY_DEFAULT_SPLASH=off restores the old behaviour.
Page and template live in the image outside the /etc/haproxy named volume;
the lists are generated on start, so image bump + recreate is the deploy.
Tests: scripts/test-default-splash.py (in the image build), new splash-off
scenario in validate-rendered-config.py.

HTTP/3 is config-only — the Debian haproxy package is built +QUIC via the
OpenSSL compat shim. Changes:
- hap_header.tpl: `limited-quic` (required to enable QUIC binds under the
compat layer) + self-healing `cluster-secret` for QUIC token derivation.
- hap_listener.tpl: `bind quic4@:443 ... alpn h3` in the shared frontend (so
real-IP/rate-limit/IP-block/Coraza rules apply to H3 too) + alt-svc header.
- Dockerfile/README: publish/document 443/udp; stamp image.version from VERSION.
- CI: tag :latest + :<VERSION> + :<sha> so there's a pinnable rollback target.
No 0-RTT (compat-layer limitation). Validated end-to-end on a standalone edge:
config parses, UDP/443 binds, alt-svc advertised, real curl --http3 -> HTTP/3.
Container must run with `-p 443:443/udp` + host UDP/443 open.

- trusted_ips.{list,map}: replace home IP with 127.0.0.1 + usage notes
- skill: resolve deploy host from gitignored target-host.local, ask if unset
(no hardcoded server FQDN); customer host in WAF test -> <live-vhost>
- README / coraza README: registry FQDN in run examples -> placeholder
- 403 block page: drop hardcoded support link -> contact provider support
- CLAUDE.md: note whitelist files ship without real IPs
- .gitignore: ignore target-host.local and *.local

- Fixed crontab permissions (600) and ownership for proper cron execution
- Added PATH environment variable to crontab to prevent command not found issues
- Created dedicated renewal script with comprehensive logging and error handling
- Added retry logic (3 attempts) for HAProxy reload with socket health checks
- Implemented host-side renewal script for external cron scheduling via docker exec
- Added crontab configuration examples for various renewal schedules
- Updated README with detailed certificate renewal documentation
This resolves issues where the cron job would not run or hang during execution.
