claude-profile modes: add deep-fable, orch pre-flight gate, ask-minimax re-point

deep-fable.md (new):
- driver: fable (claude-fable-5), same plan-first/spec-first discipline as deep
- escalates_to: opus — Opus named workflows remain available
- status line: [Fable→Opus] deep-fable · <project>: <task> | N% ctx
- on context wipe mentions "Deep Work (Fable)"

deep.md:
- Gnarly-bug consult: bg-model-call -> /ask-minimax skill with Opus fallback
- Async policy: replace bg-model-call bullet with /ask-minimax + Opus-subagent-fallback
- Workflow stance: add SSH key pre-flight check before git push

quick.md:
- Workflow stance: add SSH key pre-flight check before git push

hybrid.md:
- Async policy: replace bg-model-call reference with /ask-minimax + Opus-subagent-fallback

orch.md:
- New section "Pre-flight gate (before the autoloop)" placed before Auto-fire
- Auto-fire step 1 rewritten: run pre-flight gate first, then /loop 2m /orchestrate
- Escalation triggers: add stuck-queue row (5 iterations no change -> stop, report)
- Out of scope: add "Run the autoloop without the pre-flight gate"

context/claude-profile-modes.md:
- Status line: 47 assertions; driver table updated; 6 mode files noted
- Remaining follow-ups: bg-model-call replaced by /ask-minimax; deep-fable noted
