fix(tui): let Full Access actually grant Full Access; finish the file-search surface

Full Access is ApprovalMode::Bypass, but the deterministic Auto-Review floor
still hard-blocked calls under it: publish-like commands, destructive
background/headless work, and the Windows npm-launcher platform hold all
returned AutoReviewPlanDecision::Block. The founder's own semantics for the
posture are the opposite, and the engine already reports "Full Access" for it.

The floor now applies only in the reviewing postures (Suggest/Auto/Never).
ForcePrompt stays unchanged there; the Bypass arm of the disposition is gone
rather than merely unreachable, because it was the code that authored the
contradiction.

Existing tests updated to the posture they now describe (no new tests):
- policy-level: destroyer and publish-shape assertions run under Suggest,
  Bypass coverage asserts no hold, the Windows platform-floor test splits
  Bypass from the reviewing postures
- engine-level: the background-destructive test now requires execution
  (victim fixture asserted written) instead of a block
- child gate: a detached agent's catastrophic shell is held in Auto/Suggest/
  Never and runs under Bypass
- ACP: the Full Access case asserts one fewer failure and one more completed
  and in_progress update, matching the call that now executes

Also completes the file-search promotion rows: the eager inventory literal
gains file_search behind FIM's already-landed exclusion, the hook classifier
table gains ("file_search", "other"), the canonical-action comment no longer
calls it deferred, the zh TOOL_SURFACE mirror matches the shipped twelve, and
file_search.rs is rustfmt-clean under the repo build lock.

Names the built-in safety floor as a reviewing-posture guard in docs/MODES.md,
docs/SUBAGENTS.md and the zh mirrors.

Test evidence: nextest -p codewhale-tui focused set (auto_review, acp_server,
child_permission_gate, child_host, test_cases_08/09/11/12, subagent tests)
34 passed / 0 failed on the final run; the wider 708-test run before it passed
704 with only the four assertions updated here failing.
