fix(tui): Auto-Review safety floor: classify by verb, review unrecoverable deletes, redact the reviewer

S1 (D-1, V3): tool names are classified by verb words, not substrings.
`list_tags`, `get_latest_release`, `get_release_by_tag` and `count_tokens`
no longer trip the publish/secret floor; any mutating verb in a compound
name raises (`list_and_delete_repo` destructive, `get_or_create_*` is not a
read and is no longer benign, so it reaches review). `push`/`publish` and
destructive verbs count wherever they appear, as before; names with no
verb keep the old substring check. Bookkeeping tools (`todo_write`,
`update_plan`, `work_update`) stay reads.

S2 (D-2): an `apply_patch` deletion, or an empty `write_file`/`replace`
entry over an existing file, that git cannot restore (untracked, or dirty
against the index) goes to review instead of being allowed as a bounded
write. The check uses the read-only git review command; any failure counts
as unrecoverable. A clean tracked delete stays a routine write.

Reviewer (V7, D-8): the reviewer context passes through
codewhale_secrets model-bound redaction (new redact_json_model_bound_secrets);
a multi-word keyed value no longer masks the rest of a command line.
The reply parse accepts exactly one balanced JSON object, and a volunteered
user_authorization is capped at medium.

Not in this commit: turn-scoped holds (needs the S6 outcome ledger, not
local to auto_review.rs); `merge` on a PR noun stays External (reviewed),
not Publish, pending founder Q1.

Tests (local, focused):
- scripts/dev-cargo.sh test -p codewhale-tui --locked --lib -- auto_review reviewer approval::policy:
  79 passed; 0 failed
- scripts/dev-cargo.sh test -p codewhale-secrets --locked: 77 passed; 0 failed; 1 ignored (+1 doc: 1 passed)
- scripts/dev-cargo.sh check -p codewhale-tui --locked: clean (before the final redact.rs fix)
