Apply ch-bootstrap convention (partial)

Existing life-helper already has the Redmine project (id=12), 8 persona
categories, and Gitea remote, so this commit applies only the local-side
pieces of the cloud-handson convention:

- .claude/settings.json (safe-but-maximal permissions: allow-all + deny dangerous)
- .claude/agents/ (8 persona subagents: planner/architect/designer/developer/reviewer/qa/release/documenter)
- .claude/workflows/persona-pipeline.js
- CLAUDE.md (Design-First hard gate)
- docs/ skeleton (Diátaxis + ADR + design templates + QUEUE-PROTOCOL)
- scripts/enqueue.sh
- .env.example

.gitignore: switched .claude/ blanket-ignore to .claude/settings.local.json
so the new settings/agents/workflows actually commit. .env and nutrition/ stay ignored.

Existing root SoT files (huberman-protocols.md, habit-*.md, data-model.md,
schema/) are untouched.
