amosblomqvist 6c42393e42 feat(tools): the P2 toggle bridge — toolToggles first-class, definitive vocabulary
Reconciliation of the diverged tool-toggles seam (2026-09-19, master's
P2): Platform injected the resolved delta as an ad-hoc intersection on
AgentBuildOptions while the factories' enabled? param sat unread — the
seam was inert on both sides.

- teacher-agent: AgentBuildOptions gains toolToggles?: EnabledTools;
  both constructors thread it to the factories (createTeacherTools /
  createProberTools). An explicitly injected opts.tools registry is
  never filtered — the caller owns it.
- Vocabulary ADJUDICATED with the user (2026-09-19): TOGGLEABLE_TOOLS is
  the definitive list — the job tools only (research/demo/visual/pdf).
  quiz/ask_user_question stay always-on forever (the prober's flow is
  graded-quiz brackets -> probe_done; quiz-off collapses assessment and
  teaching doctrine is built on graded verification — the wedge danger);
  the learner-fs set, plan tools, and probe_done also always-on.
- settings-body (write side): unknown tool keys reject with 400 + the
  supported list, mirroring the prompt-switch validation; the read-side
  sanitizer stays lenient for forward-compat.
- chat-handler: the intersection is gone (field now first-class) and the
  seam comment states the adjudicated vocabulary.

Gates: typecheck, 28 new/updated tests green (tool-toggles-bridge,
question-tools, settings-body), chat-flow + settings suites green.

/**
* The P2 tool-toggle bridge (2026-09-19): AgentBuildOptions.toolToggles is
* first-class — the agent constructors thread it to the factories' enabled?
* param (an explicit opts.tools registry is never filtered), and the
* settings write side rejects unknown tool keys against TOGGLEABLE_TOOLS
* (the definitive adjudicated list — a persisted `quiz: false` would
* genuinely drop the quiz once the bridge honors the delta).
*
* Parser tests are PURE (no fs — parallel-test discipline); the agent
* construction tests use an in-memory chat fixture like
* question-tools.test.ts.
