## Why
Listing hooks by working directory alone omits hooks supplied by a thread's selected execution environments, including hooks that can block a turn.
## What changed
- Add `threadId` to `hooks/list` to return a loaded thread's current hook inventory, including selected, ready environments. Reject requests that also specify `cwds`.
- Expose `environmentId` in hook metadata and have the TUI hooks browser query the current thread and label environment-owned hooks. Keep working-directory lookup for startup review.
- Represent environment hook source paths with `PathUri` and use `LegacyAppPathString` in hook run summaries to preserve native path conventions.
## Testing
Add coverage for listing a blocking environment hook and removing it after environment failure, delivering prompt input and reporting exit status in PowerShell and Bash, and running `PreToolUse` hooks only on the command's owning executor. Extend remote network tests to verify that environment hooks use the command's network policy while retaining their filesystem access.

## Why
We need a way to list the available hooks to expose via the TUI and App
so users can view and manage their hooks
## What
- Adds `hooks/list` for one or more `cwd` values that returns discovered
hook metadata

## Review Notes
The generated schema files account for most of the raw diff, these files
have the core change:
- `hooks/src/engine/discovery.rs` builds the inventory entries during
hook discovery while leaving runtime handlers focused on execution.
- `app-server/src/codex_message_processor.rs` wires `hooks/list` into
the app-server flow for each requested `cwd`.
- `app-server-protocol/src/protocol/v2.rs` defines the new v2
request/response payloads exposed on the wire.
### Core Changes
`core/src/plugins/manager.rs` adds `plugins_for_layer_stack(...)` so
`skills/list` and `hooks/list`can resolve plugin state for each
requested `cwd`
