## What changed
- Centralize the allowlist for bundled MCP cleanup hooks and use it for both local and executor-discovered plugins, including `unified-computer-use` cleanup through `cua_repl`.
- Mark matching cleanup hooks as trusted built-ins so they run without saved hook trust and remain active when regular hooks or their per-hook state are disabled. Plugin enablement and managed-only policy still apply.
- Hide built-in cleanup hooks from hook listings and lifecycle notifications while retaining their metrics. Keep the built-in classification out of serialized protocol data.
## Testing
- Cover allowlist boundaries, trust and enablement behavior, inline and file-based hook declarations, MCP success and error responses, hook listing, lifecycle notifications, metrics, and protocol serialization.

## What changed
- Admit the curated remote Browser plugin's `Stop` and `SubagentStop` hooks when its listed `browser.turn_ended` tool matches the expected connector and is enabled by app policy.
- Carry trusted app routing metadata and the MCP environment through hook registration and execution.
- Register hooks from multiple executor environments, while deduplicating cleanup calls that share an event, MCP environment, server, and tool.
## Testing
- Cover Browser and Computer Use cleanup through separate MCP routes, including user- and managed-policy disablement.
- Verify routing metadata, environment selection, multi-environment registration, and target deduplication.

## What changed
Allow bundled browser and computer-use plugins to invoke the existing
`node_repl.turn_ended` cleanup hook for `SubagentStop` events, matching the
allowlist behavior for `Stop` and `Interrupt` events.

## Why
Executor-scoped cleanup hooks need to observe an interrupted turn as well as a
normally completed one.
## What changed
- Allow bundled executor plugins to register the allowlisted `Interrupt` hook
alongside `Stop`, while preserving multiple allowed hook entries from the
selected executor environment.
- Run interrupt hooks with the interrupted turn's last step discovery and turn
metadata. Turns without a step context do not reuse discovery from an earlier
turn.
- Keep executor-scoped interrupt hooks asynchronous and omit public hook
lifecycle events for them, matching executor `Stop` hook behavior.
## Testing
Added coverage for hook filtering and registration, interrupt execution and
metadata propagation, environment selection, and turns without a step context.

## Why
Executor plugin manifests are unsigned, so cleanup hooks must remain limited to
explicitly trusted plugin identities and MCP targets.
## What changed
- Allow the bundled Browser, Chrome, Chrome Dev, and Chrome Internal plugins to
run the existing `Stop` hook for `node_repl.turn_ended`.
- Continue allowing the bundled Computer Use plugin and rejecting unlisted or
lookalike marketplace identities.
## Testing
- Extend manifest-filtering coverage for unlisted bundled plugins and marketplace
name variants.

## What changed
- Discover inline hooks from executor-provided plugin manifests and accept only
the bundled Computer Use `Stop` hook for `node_repl.turn_ended`.
- Add the accepted hook to the current step's hook engine with
executor-scoped provenance.
- Run executor-scoped hooks in the background after regular stop-hook
decisions, without delaying turn completion, applying control effects, or
exposing them in hook summaries. Skip them when regular hooks only block
continuation.
## Testing
- Added coverage for manifest filtering and option preservation.
- Added coverage for background execution, interaction with regular stop
hooks, and non-blocking turn completion.
