feat(codex): SDD dispatch routing, fork hygiene, and final-review wave termination

Codex SDD runs at frontier tiers spin out: subagents inherit the
session's model and effort, review seats find real-but-endless defects
every round, and the final whole-branch review has no reachable
termination state. Field forensics across multiple real sessions traced
the mechanism: spawn_agent's fork_turns defaults to "all" (full-context
forks that also refuse model overrides), omitted model/effort params
inherit the frontier parent, and dispatch rules loaded at session start
do not survive context compaction — a compacted controller reverts to
inheritance exactly when the session is longest and most expensive.

Three coordinated changes:
- codex-tools.md: every SDD spawn sets fork_turns "none" plus explicit
  model/reasoning_effort when the schema supports them (Codex 0.145+),
  with an inheritance warning for older builds; reviewer tier never
  exceeds implementer tier and fix rounds never get effort bumps.
- task-brief/review-package print a dispatch tuple with their output
  (review-package grows --role for re-review/final-review), putting the
  routing values in front of the controller at the moment of dispatch —
  reprinted every round, so they survive compaction by construction.
- SKILL.md: the final-review wave closing is policy, not a verdict —
  one fix dispatch, one scoped re-review, residuals adjudicated to the
  ledger; one-off review procedures never become standing; Model
  Selection defers to platform role tables where one exists.

Validated live: a previously spun-out 14-task run (8h, 6 tasks, died
mid-loop) re-executed to completion under these changes — bounded fix
loops, single-cycle final review, ~20 consecutive correctly-routed
dispatches across two compactions. Reviewer-tier matrix (125 cells)
showed no calibration cost: clean-diff approvals and planted-defect
recall are identical across tiers. Eval scenarios to follow before any
upstream submission.
