- PR #82243: feat(tools): compose deferred tools in execute_code

These issues and PRs concern missing or incorrect session_id and tool_call_id fields in pre_tool_call plugin hooks across multiple call sites, including nested tool execution. Related feature work covers request-scoped hooks, tool call correlation IDs, and hook-based blocking of tool execution.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
- Members outside that structural core may belong to a different underlying problem.
- Pairwise link density `0.14`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
