feat: Add Kimi agent workspace with development scaffolding

Create the Kimi (Moonshot AI) agent workspace per AGENTS.md conventions:

Workspace Structure:
- .kimi/AGENTS.md - Workspace guide and conventions
- .kimi/README.md - Quick reference documentation
- .kimi/CHECKPOINT.md - Session state tracking
- .kimi/TODO.md - Task list for upcoming work
- .kimi/notes/ - Working notes directory
- .kimi/plans/ - Plan documents
- .kimi/worktrees/ - Git worktrees (reserved)

Development Scripts:
- scripts/bootstrap.sh - One-time workspace setup (venv, deps, .env)
- scripts/resume.sh - Quick status check + resume prompt
- scripts/dev.sh - Development helpers (status, test, lint, format, clean, nuke)

Features:
- Validates Python 3.11+, venv, deps, .env, git config
- Provides quick status on git, tests, Ollama, dashboard
- Commands for testing, linting, formatting, cleaning

Per AGENTS.md:
- Kimi is Build Tier for large-context feature drops
- Follows existing project patterns
- No changes to source code - workspace only

.kimi/scripts/dev.sh
