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)

+# Working in this repo
+
+This repo is the global AI development configuration repository — the authoritative source for agent definitions, skills, workflows, and prompts across all projects.
+
+## Structure
+
+- `core/` — provider-agnostic source of truth (plain language, no tool-specific references)
+- `.agents/skills/` — canonical skills location (Agent Skills standard); populated in Chunk 3
+- `providers/claude-code/` — Claude Code adapter (deployed to `~/.claude/` via `install.sh`)
+- `docs/` — project documentation, PRDs, and issues
+- `scripts/` — install.sh (sync.sh and init-project.sh come in Chunk 6)
+- `tests/` — test scripts
+
+## Key documents
+
+Read these at the start of every session in this repo:
+
+- `CONTEXT.md` — domain language and principles; challenge any term that conflicts with it
+- `docs/VISION.md` — purpose, goals, roadmap, and long-term Management Application vision
+
+## Key rules
+
+- `core/` content must use plain imperative language — no tool names, provider APIs, or format assumptions
+- Never edit files deployed by `sync.sh` directly in a project; put customizations in override files
+- `providers/claude-code/CLAUDE.md` is the deployed global config — edit it there, not here
+
+## Chunk development workflow
+
+Each chunk follows this sequence:
+1. `/grill-with-docs` — grill vision/context before writing anything
+2. `/to-prd` — write the PRD from the grilling output
+3. `/to-issues` — break PRD into issues (`docs/issues/` until Gitea is set up)
+4. `/tdd` — implement each issue using TDD
+5. `/improve-codebase-architecture` — architecture review after implementation
+6. Start a new session before the next chunk
+
+Don't skip `/tdd` — it's the easy one to forget.
