Moves investigation ID persistence and _CacheManager class from ai.py
into a dedicated cache module. No behavior changes.
Moved: _load_investigations, _save_investigations, _get_investigation_id,
_CacheManager (all methods), _sha256_path, CACHE_ROOT, INVESTIGATIONS_PATH.
Also added a local _now_iso() in cache.py to avoid a circular import
(ai.py imports from cache.py).

Adds think, checkpoint, and flag tools for agent reasoning visibility:
- think: records observation/hypothesis/next_action before investigation
- checkpoint: summarizes learned/unknown/next_phase after file clusters
- flag: marks notable findings to flags.jsonl with severity levels
Additional changes:
- Step numbering in investigation system prompt
- Text blocks from agent now printed to stderr (step labels visible)
- flag tool available in both investigation and synthesis passes
- analyze_directory() returns (brief, detailed, flags) three-tuple
- format_flags() in report.py renders flags sorted by severity
- Per-directory max_turns increased from 10 to 14

When the 70% context budget is hit mid-directory, the early exit now
writes a partial directory cache entry from whatever file summaries
the agent cached in prior turns, instead of discarding the work.
If file entries exist: concatenates their summaries into a directory
entry marked partial=true. If no files were cached: writes a minimal
entry noting the budget was reached before processing.

Adds branch naming, commit message format, and merge procedure.
All future changes must start on a branch and merge to main with --no-ff.

- setup_env.sh creates ~/luminos-env venv and installs all AI packages
- CLAUDE.md updated to reflect the new dependency model: base tool is
zero-dep, --ai requires packages installed via venv
- Documents the capabilities module and updated ai.py architecture

- --install-extras: prints status of all optional AI packages
- --clear-cache: wipes /tmp/luminos/ investigation cache
- --fresh: forces a new investigation ID, ignoring cached results
- AI import is now lazy (only when --ai is used) so the base tool
never touches optional dependencies
- target argument is optional when using --install-extras

Rewrites ai.py from a single Claude API call into a multi-pass,
cache-driven agent architecture:
- Per-directory isolated agent loops (max 10 turns each) with context
discarded between directories
- Leaves-first processing order so child summaries inform parents
- Disk cache (/tmp/luminos/{uuid}/) persists across runs for resumability
- Investigation ID persistence keyed by target realpath
- Separate synthesis pass reads only directory-level cache entries
- Replaces urllib with Anthropic SDK (streaming, automatic retries)
- Token counting with 70% context budget threshold for early exit
- parse_structure tool via tree-sitter (Python, JS, Rust, Go)
- python-magic integration for MIME-aware directory listings
- Cost tracking printed at end of investigation

Introduces luminos_lib/capabilities.py as the single source of truth for
optional package availability. Detects anthropic, tree-sitter, python-magic
and their grammar packages. Provides check_ai_dependencies() for gating
--ai mode and print_status() for --install-extras. Also hosts clear_cache()
to avoid pulling heavy AI imports for cache cleanup.

Adds --ai flag that sends the directory tree, file categories, and
sampled file contents to Claude for analysis. Produces a brief
summary at the top of the report and a detailed breakdown at the
end. Requires ANTHROPIC_API_KEY env var; degrades gracefully without it.
Uses only stdlib (urllib) to keep the zero-dependency constraint.
