Strengthen stage handoffs and add /kw:lfg (CE-style loop runner)

[crowlede]

Summary

Compound Knowledge’s loop stages were easy to lose mid-conversation compared with Compound Engineering: brainstorm could end without a clear “now plan” handoff, and there was no hands-off runner like CE’s /lfg.

This PR:

1. Strengthens stage orientation + handoffs across /kw:brainstorm, plan, review, work, compound, and confidence
   • Explicit **Stage: …** banners
   • Mandatory end-of-stage menus (“Brainstorm complete”, “Plan complete”, etc.) that must not be skipped
   • Selecting the next skill immediately loads it
   • AskUserQuestion capped at 4 options (CE parity); larger menus fall back to a numbered list
2. Adds /kw:lfg — knowledge-work counterpart to CE /lfg
   • Hands-off: plan → review → work → compound via mode:pipeline children
   • Offered as Ship the rest with /kw:lfg (hidden while load-bearing brainstorm questions remain)
   • P1 review findings are a hard gate; ends at deliverables + docs/knowledge/ (no PR/CI)

CE /lfg → CK mapping

CE /lfg	CK /kw:lfg
plan → work → simplify → code-review → PR → CI	plan → review → work → compound
Terminal: open PR	Terminal: deliverables + compounded learnings
Entry: feature / requirements plan	Brainstorm origin, topic, or existing plans/*.md
mode:pipeline / return-to-caller	mode:pipeline on each child; children do not self-chain

CE core-loop verification (done on this draft)

Ran plan → multi-lens review → fix against this PR before asking maintainers to merge:

Finding	Sev	Status
AskUserQuestion menus >4 options	P0	Fixed — cap + numbered-list overflow
Compound “never auto-save” vs LFG auto-approve	P0	Fixed — pipeline exception
disable-model-invocation used as pipeline flag	P1	Fixed — mode:pipeline carrier
Plan/work interactive waits blocked LFG	P1	Fixed — explicit pipeline skips
Bare plans/*.md re-planned under LFG	P1	Fixed — non-brainstorm plans skip to review
Incomplete handoff handlers / “Ship it” naming	P1	Fixed

Still draft until you smoke-test interactively (see test plan).

Test plan

• /kw:brainstorm ends with Brainstorm complete + menu; picking plan loads /kw:plan
• Menus with >4 options render as a numbered list (no AskUserQuestion validation error)
• Ship the rest with /kw:lfg writes origin doc then runs plan → review → work → compound without stage check-ins
• LFG option hidden when load-bearing brainstorm questions remain open
• /kw:lfg plans/strategy-….md (or plan:…) skips planning and starts at review
• Unresolved P1s stop LFG before work
• Mid-loop stage banners stay clear

Version

1.1.0 (plugin.json, marketplace.json, CHANGELOG, README counts).

CE core-loop verification note

Ran this draft through a Compound Engineering-style plan → review → fix pass before marking ready:

P0 fixed: AskUserQuestion 4-option cap + numbered-list overflow; compound pipeline auto-save exception so /kw:lfg no longer contradicts “never auto-save.”

P1 fixed: mode:pipeline carrier (replacing disable-model-invocation as a mode flag); children return-to-caller instead of self-chaining; plan/work wait skips under pipeline; existing plans/*.md paths skip re-planning; handoff handlers completed; “Ship the rest” / “Done for now” naming.

Still leaving this as a draft for a quick interactive smoke test of the menus + one /kw:lfg dry run in Claude Code/Cursor before ready-for-review.
