#2194 extended `im +messages-search` to `AuthTypes: {user, bot}` but left the
affordance example and the skill reference asserting user-only, so the
dual-identity guard added by #2199 fails on main.
* fix(schema): fall back to runtime catalog when no embedded metadata
Binaries built from the bare Go module (plugin builds) embed only the
empty meta_data_default.json stub because meta_data.json is gitignored
and fetched at build time. The schema command, its completion, and the
affordance command-form resolver read the embedded-only catalog, so
every schema lookup failed with "Unknown service" even though the
runtime registry had already sync-fetched full metadata.
Add registry.SchemaCatalog(): embedded when compiled in (official
builds unchanged, still deterministic), otherwise the merged runtime
catalog seeded from cache or remote fetch. When neither source has
data (offline plugin build with a cold cache), schema now returns a
failed_precondition error with an actionable hint instead of
"Unknown service" with an empty candidate list.
* fix(registry): gate cached meta overlay on version newer than embedded
The cached remote meta was overlaid onto the embedded meta_data.json
unconditionally, so after a CLI upgrade an equal- or older-version
cache kept shadowing the freshly shipped embedded definitions until a
later refresh happened to rewrite it.
Only overlay when the cache version is strictly newer than the
embedded baseline. The bare-module stub baseline is "0.0.0", so plugin
builds without compiled metadata still take any real cached version
(TestOverlayGate_StubEmbedded_OverlaysRealCache) and the schema
runtime fallback keeps working offline from a warm cache.
Ports #1376 onto the typed meta model.
