docs(events): fix stale turn-mirror / tools-execute prose caught in review

Browse Source 
Codex review of the interception-seams merge flagged current-state prose still
describing removed/renamed surfaces:

- packages/core/agent/src/types.ts module doc: the agent/* "transient emits"
  list still ended with "the turn boundaries" — corrected to state turn/step
  boundaries are durable session/event records, not agent/* emits, and to list
  the actual interception seams (prompt-submit/pre-step/request/step-result/
  turn-continuation) + agent/session-start.
- interception-seams RFC: "agent/turn-end fires and the ACP bridge settles" →
  the durable turn/end is appended and ACP settles off it (no turn mirror).
- two proposed RFCs (acp-agent-client-protocol, optional-code-mode) named the
  pre-split `tools/execute` waterfall → the `tools/pre-execute`/`tools/post-execute`
  pair.

Regenerated the cordis catalog (module-doc change). No code/behavior change.

### Three load-bearing loop decisions
1. **Always open the turn first; a fully-blocked batch is a zero-step `rejected` turn.** `prompt-submit` fires AFTER `turn/start`, per message. A batch whose every prompt is blocked does NOT skip the turn — it opens a zero-step turn that closes with `rejected`. This one move resolves three problems at once: (1) turn-enclosure holds (every event has an open turn to live in); (2) `agent/turn-end` fires and the ACP bridge settles normally (mapping `rejected`→`cancelled`) instead of hanging; (3) the block reason is a durable in-turn fact. An `allow`'s `additionalContext` is `inject()`ed into this now-open turn.

An `allow`'s `additionalContext` is `inject()`ed into this now-open turn.
2. **Post-tool `additionalContext` is buffered and appended AFTER all `tool/result`s.** `content`/`feedback` shape the result `execute()` returns, but `additionalContext` is a SEPARATE `context/message`, and a single step can carry multiple tool calls. Appending context right after each result would interleave `result(c1) → context → result(c2)` and break tool-call/result adjacency. So `execute()` surfaces `additionalContext` on its `ToolExecutionResult`, and the loop buffers every per-call context for the step and appends them as `context/message`(s) only after every `tool/result` is appended.
