Code review follow-up for the dual-boot hang fixes:
- Outer tool wrap aborts a linked AbortController on timeout so nested work (npx) stops
- fn_skills_install uses SIGTERM then delayed SIGKILL instead of immediate double-kill
- clearHostTaskStores only drops external entries (does not wipe unrelated CLI boot state)
- Align import/browse schema max with the 50-item hard clamp
- Tests for host-store cache injection and timeout-driven signal abort
