Guillaume Meyer 5cbe0b1c4f test(plugins): cover _discover_all_plugins recursion + cross-link loader
Add a TestDiscoverAllPlugins class covering the six cases the recursive
scan needs to handle:

- flat plugin uses its manifest ``name:`` as the key
- category-namespaced plugin keys off ``<category>/<dirname>`` even when
  the manifest ``name:`` is bare (regression test for the original bug —
  ``plugins/observability/langfuse/`` with ``name: langfuse`` must
  surface as ``observability/langfuse``, not ``langfuse``)
- user-installed plugin overrides bundled on key collision
- depth cap: anything below ``<root>/<category>/<plugin>/`` is ignored
- bundled ``memory/`` and ``context_engine/`` are skipped (they have
  their own loaders), but user plugins under those category names are
  still scanned

Also add an in-source comment next to the key derivation pointing at the
loader's matching line (``PluginManager._parse_manifest`` in
plugins.py:1027-1028), so future renames of one site flag the other.

Both items raised in Copilot review on #27161.
