🔐 fix: Preserve Plugin MCP Provenance Through Registry Storage (#14744)
* 🔐 fix: Preserve Plugin MCP Provenance Through Registry Storage

Agent Plugins MCP servers are tagged `source: 'plugin'` by the plugin
loader so `processMCPEnv` returns them verbatim, keeping any `${VAR}` a
plugin declared literal. The registry derived `source` from the storage
tier alone, so every startup server routed through
`addServer(..., 'CACHE')` was retagged `'yaml'` — before inspection and
again before persistence.

That dropped the marker for deployment plugin servers merged into the
startup MCP config, so `processMCPEnv` treated plugin-authored strings as
operator-authored templates and expanded them from `process.env`. A
malicious plugin declaring `Authorization: Bearer ${OPENAI_API_KEY}`
received the host's key at its own endpoint, at both boot-time inspection
and every runtime connection.

`resolveServerSource` now carries an existing plugin marker through
instead of re-deriving it, and is applied at all four tag sites
(`addServer`, `addServerStub`, `inspectServerUpdate`, and config-tier
lazy init, which hardcoded `'config'` and would have re-opened the same
hole). The marker is only honored for operator-loaded tiers: a DB entry
is user-authored and stays `'user'`, so user input cannot claim plugin
provenance to escape the sandboxed placeholder rules.

* 🔒 fix: Address Codex review — config-override provenance & upgrade re-tag

Two follow-ups from the Codex review of the provenance fix, plus a test
cleanup.

P2 — a Config-tier override that shadows a same-name plugin base inherited
the base's `source: 'plugin'` through the merge in `getServerConfig` /
`getAllServerConfigs`, so `processMCPEnv` stopped resolving the operator's
own `${VAR}` placeholders and silently broke their server. New
`overlaySource` helper keeps an operator override on its own trusted
source when the base is plugin-sourced; all other bases still inherit as
before. Fails safe (never a leak), but the regression is real.

P1 — the init fingerprint hashes only the raw MCP config, which already
carried `source: 'plugin'` before the provenance fix, so the hash is
unchanged by it. On a Redis-backed rolling restart with no config change,
followers short-circuit on the stale `INITIALIZED_CONFIG_HASH` and the
old `source: 'yaml'` plugin entries survive with no expiry — the fix
never takes effect. Fold a `REGISTRY_STORAGE_SCHEMA_VERSION` into the
fingerprint so an upgrade forces exactly one cluster-wide re-init.

Also drop unnecessary `as` casts in the provenance tests (declare the
fixture as `ParsedServerConfig`, assert with `toMatchObject`) and add a
regression test for the P2 override case.
