chore: bootstrap repo with chunks 1 and 2

Establishes the global AI development config repo from scratch:

- Chunk 1: repo skeleton, install.sh, statusline, deploy manifest
- Chunk 2: core instructions (coding/git/testing), CLAUDE.md rewrite
  (always-on + content index two-tier model), docs restructure,
  6 ADRs, ROADMAP.md, .gitkeep placeholders
- Bootstrap skills in .claude/skills/ (to be catalogued and migrated
  to .agents/skills/ in Chunk 3)

+# 0008 — Restructure docs/ subdirectories and migrate existing PRD ✅
+
+## What to build
+
+Create the subdirectory-by-type structure under `docs/` as defined in CONTEXT.md. Migrate the one existing PRD from its flat location to the correct subdirectory. No other files move.
+
+New directories to create: `docs/prd/`, `docs/ard/`, `docs/bug/`, `docs/notes/`, `docs/adr/`. (`docs/issues/` already exists and is correctly placed.) `docs/VISION.md` stays at `docs/VISION.md`.
+
+Migration: `docs/prd-chunk-1.md` → `docs/prd/chunk-1.md`.
+
+## Acceptance criteria
