feat(2): discourse Q4.6 policy-compliant shape (plan §9) — env-var start_period, delete cc-ci overlay, upgrade N/A

Migrate discourse off the cc-ci compose overlay per plan §9 / plan-prefer-env-over-compose-overlay.md:
- recipe_meta: drop UPGRADE_BASE_VERSION + COMPOSE_FILE + CHAOS_BASE_DEPLOY; set APP_START_PERIOD=1200s
  via EXTRA_ENV (the recipe-PR exposes start_period: ${APP_START_PERIOD:-5m}); declare upgrade tier N/A
  (both published prev bases pin removed bitnami images; Adversary §7.1 granted, REVIEW-2 efe3790).
- delete tests/discourse/compose.ccci-health.yml + install_steps.sh (existed only to copy the overlay).
- DECISIONS.md + STATUS-2 record the §9 guardrail + discourse shape (upgrade N/A, env start_period,
  pg_backup restore-hook recipe-PR = 5th data-loss recipe cc-ci caught).
recipe-PR head now 8b8df17 (start_period env var added). Not a claim — run STAGES=install,backup,restore,custom next.

#!/usr/bin/env bash
# discourse — INSTALL-TIME hook (Phase 2 Q4.6). Runs during the install tier AFTER `abra app new` +
# EXTRA_ENV + `abra app secret generate` and BEFORE the single `abra app deploy`
# (lifecycle.py::_run_install_steps), with CCCI_RECIPE / CCCI_APP_DOMAIN / CCCI_APP_ENV in env.
#
# Purpose: provide the cc-ci deploy overlay `compose.ccci-health.yml` (app healthcheck start_period
# bump) into the recipe checkout so recipe_meta's COMPOSE_FILE (compose.yml:compose.ccci-health.yml)
# resolves. Without the larger start_period, discourse's 15-25min Rails cold boot is killed mid-boot
# by the recipe's 5m-start_period healthcheck and the deploy never converges (see the overlay header).
# The overlay is an UNTRACKED file in the recipe repo, so `git checkout -f` (the upgrade tier's
# re-checkout to PR head) preserves it — COMPOSE_FILE keeps resolving across install AND upgrade
# deploys. CHAOS_BASE_DEPLOY=True (recipe_meta) lets the pinned base deploy proceed despite this
# untracked file (abra's clean-tree check would otherwise FATA).
