## What changed
- Return qualified skill names such as `team:deploy` and parsed `dependencies` and `policy` instead of a separate namespace and raw metadata file. Share `agents/openai.yaml` parsing and validation between skill loaders and executor discovery.
- Include each standalone skill's search-root ID and path in `discoveryRoot`, while accepting responses from older executors that omit it.
- Add plugin `displayName`, falling back to the manifest name or installation directory.
- Materialize inline MCP declarations in `mcpConfig` with the manifest as their source path, and report incomplete discovery when declared MCP or Apps configuration files have no returned contents.
## Testing
Add coverage for JSON round trips, omitted `discoveryRoot`, optional and invalid skill metadata, qualified names, display-name fallbacks, and inline MCP configuration. Verify standalone search roots survive cached discovery and sandboxed RPC responses.

## What changed
- Register `capabilities/discoverV2` for initialized sessions and expose it through `ExecServerClient` and remote `Environment` APIs, checking executor support before calling it.
- Reuse startup discovery locations and retry failed prewarming on demand. Replay discovery once after executor recovery while preserving the request parameters.
- Track whether all required filesystem watches registered successfully and reload locations and metadata on each request when registration fails.
## Testing
Add coverage for RPC metadata refresh, omission of skill instruction bodies, sandbox isolation, startup scan recovery, disconnect replay, and successful or failed watch registration.
