feat(brain): /morning start-of-day routine (phase 1 — core)

[Jammy2211]

Add a /morning composition skill (PyAutoBrain) — a human-driven start-of-day routine that brings the workspace to a clean, current, known-good state and surfaces the day's actionable items. Composes existing doors (/health, later /hygiene) plus two workspace-ops scripts; owns no new state (a skill, like /route).

Full spec: PyAutoMind/feature/pyautobrain/morning_routine.md. This issue is Phase 1 (core); Phase 2 (overnight-cron sweep, version-pin drift, resume-context, /hygiene, richer digest) follows as a separate PR.

High-level plan

• Move the two untracked workspace-root scripts (pull_all_main.sh, clean_slate.sh) into PyAutoBrain/bin/ (tracked; resolve the workspace root, not admin_jammy).
• Add skills/morning/morning.md + SKILL.md orchestrating: sync → clean-slate → consult /health → prioritized digest.
• Guardrail: auto-run only the non-destructive steps; surface deletes/edits/bumps for approval.
• Wire into bin/install.sh + the command veneer (skills/COMMANDS.md, AGENTS.md verb table).
• Verify end-to-end on the live workspace.

Detailed plan

1. Scripts → PyAutoBrain/bin/ (pull_all_main.sh, clean_slate.sh): change ROOT from "script dir" to the workspace root (two levels up from bin/); keep DRY_RUN + per-repo reporting; chmod +x.
2. skills/morning/morning.md: orchestration body (~30–50 lines, /route shape): (1) bin/pull_all_main.sh — report off-main/dirty/behind/diverged; (2) bin/clean_slate.sh; (3) consult /health (readiness verdict, release status, red CI, worktrees); (4) emit digest (🚨 blocking · ⚠️ drifted · 🧹 cleanable · ✅ clear-to-work). Note the auto/approve guardrail + "compose, don't recompute." SKILL.md: thin wrapper.
3. Wiring: ensure /morning installs via bin/install.sh (skills/ scan); add /morning to skills/COMMANDS.md veneer + AGENTS.md command-surface verb table.
4. Verify: bash bin/install.sh; invoke /morning; confirm sync+clean+health+digest render; bin/check_skill_line_counts.sh passes.

Testing

• DRY_RUN=1 bin/clean_slate.sh + bin/pull_all_main.sh from the new location — confirm workspace-root resolution.
• bash bin/install.sh → /morning appears; invoke end-to-end.

Branch: feature/morning-routine · Phase 2 tracked in the Mind spec.

[Jammy2211]

Phase 1 implemented in #106 (pending-release): /morning skill + bin/pull_all_main.sh / bin/clean_slate.sh + docs. Verified: scripts syntax + workspace-root resolution, install discovery, check_skill_line_counts OK, test_skill_install.py 7 passed. Phase 2 tracked in PyAutoMind/issued/morning_routine.md.
