## Why
Enabling, disabling, or reinstalling a cached remote plugin can change its
effective MCP servers, hooks, and skills without materializing a new bundle.
These transitions need to invalidate plugin consumers just like bundle updates
and removals do.
## What changed
- Report a unified set of changed remote plugins and their affected
capabilities for materializations, removals, and installed-state changes.
- Derive enablement and reinstall changes by comparing installed snapshots,
while keeping materialization metadata separate for hook trust handling.
- Preserve removal notifications even when stale cache cleanup fails, and use
all reported changes to refresh loaded plugin state and runtime consumers.
## Testing
Added coverage for cached plugin enablement, disablement, removal, and
reinstallation, including removal when cache cleanup cannot complete.

## Why
Remote plugin sync results need to identify which runtime categories may require
invalidation when a cached bundle changes.
## What changed
- Add `RemotePluginCapabilities` hints for MCP servers, Apps, hooks, and skills.
- Attach capability hints to materialized and removed plugins. Updates union the
declarations from the old and new bundles, while removals inspect the active
bundle before deleting its cache.
- Discover declarations without applying runtime policy or creating runtime
data directories.
## Testing
- Cover Agent Plugin capability discovery with an unavailable runtime data
directory.
- Cover capability accumulation across bundle versions and removal reporting.

## What changed
- Carry newly installed or updated remote plugin metadata through effective-plugin refresh callbacks, including coalesced refreshes.
- After a successful refresh, record the current hook hashes for listed workspace plugins associated with the active account while preserving existing hook settings and unrelated state.
- Serialize the background trust write with config mutations, and leave hooks untrusted if the write fails or the active account changes.
## Testing
- Cover eligible plugin selection and escaped hook config keys.
- Verify end-to-end trust for newly materialized plugin hooks, preservation of existing config, and fail-closed behavior when config cannot be written.
