A plugin's update diff now includes its marketplace.json entry as a
pretty-printed "marketplace.json entry" file, so inline hooks, MCP servers
and commands are reviewed like any file. CatalogItem gains
plugin_components (entry / plugin.json runnable keys, hooks/hooks.json,
.mcp.json, commands/), and installing a plugin now goes through
PluginConfirmModal listing them. The import-preview warnings describe
that confirmation accurately.

GitTree::read_file now takes a cap and reads the object's size from its
header first, so a blob over MAX_MANIFEST_BYTES / MAX_ITEM_BYTES is refused
without being inflated, and the blob is taken rather than cloned.

Fix round 1 from PR review of the tree/catalog parsing:
- collect_dir now rejects an entry whose name is ".", "..", empty, or
contains "/", "\" or NUL before it becomes part of an item's rel_path —
a crafted git tree could otherwise walk a file outside the item's own
folder once that path is joined against the item root downstream.
- collect_dir caps recursion at 32 directory levels and counts
directories (not just files) toward MAX_ITEM_FILES, so a tree that is
wide or deep rather than merely file-heavy is still bounded.
- hook.json and plugins/.claude-plugin/marketplace.json are now rejected
unparsed above 1 MiB, rather than handed to serde_json regardless of
size.
A pre-read size query (checking a blob's size before reading it) is
deferred per controller ruling — this round reads the blob and checks
its length before parsing, which is enough for the JSON-parsing DoS
shape being closed here.
