v2.14.2 — /phx:full --codex + watch-pr trigger-gate fix

Patch release: extend the optional Codex reviewer to the autonomous full
loop (/phx:full --codex) and fix a false-skip in the /phx:watch-pr --codex
trigger gate surfaced in live use.

Added

• /phx:full --codex — the Codex CLI joins the review panel on every
  review cycle of the autonomous full loop, parity with /phx:review --codex.
  The flag propagates through both review paths (inline /phx:review and the
  delegated parallel-reviewer, which now spawns codex-reviewer as a
  conditional cross-model track). Consensus findings (a Claude agent and
  codex) are marked HIGH CONFIDENCE. Requires the codex CLI; degrades to a
  SKIPPED note when absent — never fails the cycle. Users without codex are
  unaffected (flag-gated, no codex code paths without --codex).

Fixed

• /phx:watch-pr --codex no longer skips the @codex review trigger based
  on the wrong signal — the "already reviewed → don't post" gate is now
  strictly scoped to the connector bot (chatgpt-codex-connector[bot])
  reacting to / reviewing the current head SHA. The repo's CI "Codex" check
  and local codex exec / /phx:review --codex / /phx:codex-loop runs are
  explicitly named as separate mechanisms that never satisfy the skip. With
  --codex, the default is now unambiguously to POST the trigger (the flag is
  that consent); skipping is the narrow exception.
