launch.sh: phase-aware sequencer (run 1c -> auto-transition 1b -> stop for manual gate)

Make the launcher drive an ordered phase sequence (default 1c then 1b). Each phase has its own
plan + phase-namespaced loop-state files (STATUS-<id>.md/BACKLOG/REVIEW/JOURNAL); the watchdog
auto-transitions when the current phase's STATUS-<id>.md shows ## DONE, and STOPS after the last
phase (writes SEQUENCE-COMPLETE, exits) as a manual gate before Phase 2. start_agent injects a
phase preamble (source-of-truth = phase plan; phase-namespaced state) ahead of the base role
prompt. DONE detection reads the builder's local clone (reliable, no push-lag). Handoff signalling
+ resilience preserved and made phase-scoped (reset baseline on transition).

# launch.sh — start and supervise the two cc-ci autonomous loops + a watchdog.
# launch.sh — start and supervise the two cc-ci autonomous loops + a phase-aware watchdog.
#
# Model (see plan.md §6 / §6.1): two INDEPENDENT Claude Code sessions —
# • Builder (tmux session: cc-ci-builder) working clone /srv/cc-ci/cc-ci
# • Adversary (tmux session: cc-ci-adv) working clone /srv/cc-ci/cc-ci-adv
# coordinating only through the git repo on git.autonomic.zone.
#
# Each agent self-paces with a `/loop` (ScheduleWakeup) — that handles ITERATION.
# This script's watchdog handles RESILIENCE: it restarts a session that has died
# and stops everything once STATUS.md reports "## DONE".
# PHASES: the watchdog runs an ordered sequence of sub-phases (default: 1c then 1b). Each phase
# has its own plan + phase-namespaced loop-state files (STATUS-<id>.md etc.). When a phase's
# STATUS-<id>.md shows "## DONE", the watchdog AUTO-TRANSITIONS to the next phase; after the LAST
# phase it STOPS the loops and exits (a manual gate — e.g. check in before Phase 2).
#
# Three jobs: ITERATION (each agent's /loop), RESILIENCE (restart a dead loop), HANDOFF SIGNALLING
# (ping the waiting loop the moment its counterpart hands off), PHASE SEQUENCING (this file).
#
# Usage:
# ./launch.sh start # start both loops + watchdog (idempotent)
# ./launch.sh start # start the sequence at phase 0 + watchdog (stops/relaunches loops)
# ./launch.sh watchdog # run only the supervision loop in the foreground
# ./launch.sh status # show session + DONE state
# ./launch.sh status # show phase + session + DONE state
# ./launch.sh logs builder|adversary|watchdog # tail a session/log
# ./launch.sh stop # stop both loops + watchdog
#
# Configure via env vars (defaults below). At minimum set CC_CI_REPO once the
# Builder has created the repo, so the watchdog can detect DONE.

*** cc-ci SUB-PHASE ${pid} ***
SINGLE SOURCE OF TRUTH for THIS phase: /srv/cc-ci/cc-ci-plan/${plan} — read it in full now; it defines this phase's mission and Definition of Done.
The general loop protocol still applies and lives in /srv/cc-ci/cc-ci-plan/plan.md (§6.1 coordination, §7 pacing, §9 guardrails) — read those sections too.
Track loop state in PHASE-NAMESPACED files in your repo clone: ${status}, BACKLOG-${pid}.md, REVIEW-${pid}.md, JOURNAL-${pid}.md. DECISIONS.md is shared (append).
"Done" for this phase = the Builder writes "## DONE" to ${status} ONLY after every Definition-of-Done item is Adversary-verified with a fresh PASS in REVIEW-${pid}.md (handshake per §6.1).
The repo's Phase-1 STATUS.md / BACKLOG.md / REVIEW.md are HISTORY from the completed Phase 1 — do NOT use them as your state; use the phase-namespaced files above.
Wherever the standing rules below say "plan.md"/"STATUS.md"/"BACKLOG.md"/"REVIEW.md", substitute the phase plan and these phase-namespaced files.
