fix: codex adversarial fixes — JSON trust, fail-open visibility, user-state safety

Codex outside-model adversarial pass (inline-diff workaround for the
sandbox), P1/P2 findings triaged cross-model:
- Parent validates the dispatch JSON's field types and treats
  documentation_section as untrusted markdown (Step 19's redaction scan
  covers the final body; instruction-shaped text inside it is never
  followed). The error branch now explicitly skips items 2-6.
- Remote-ahead divergence is named, not silent: the parent lists foreign
  commits before creating a PR over a moved branch.
- Recovery cleanup never discards content: stray staged doc edits are
  unstaged but never checked out or cleaned away.
- Greptile UNAVAILABLE gets a concrete PR-body line, not a vague
  'wherever results are reported'.
Pre-existing-class P1s (self-asserted spawned trust chain, unenforceable
foreground timeout) are cross-model confirmed and tracked: PreToolUse
hook TODO at P1, harness-residue hazard documented.
