This PR reorganizes and aligns docs around the full vision — version your thoughts — and sets groundwork for Human+AI co‑thought, while removing experimental Neo4j artifacts.

Highlights

  • README: rewritten with the full vision (serverless, distributed thought‑graph), Quickstart with outputs, Human+AI Co‑Thought section, and embedded logo.
  • Docs reorg: added planning/specs/testing/deployment/requirements/risk/charter with TOCs; docs/README index; cross‑links.
  • PRD: Co‑Thought MCP service (local‑only) with endpoints, flows, acceptance criteria.
  • Architecture: refreshed ARCHITECTURE.md to match current focus; Attribution doc now includes a Lanes & Filters quickstart.
  • Audit: added docs/audits/vision-drift.md with findings + remediation plan.
  • AGENTS.md: added Vision Snapshot and docs linter guardrails; removed internal Neo4j content.
  • Hygiene: removed MIGRATION_STATUS.md (stale); tightened .gitignore; untracked quality reports and sample outputs; quarantined stray build artifacts and Neo4j scripts under .trash.

Why now

  • Establishes a clean onboarding/readme and a coherent documentation map.
  • Captures the co‑thought direction without gating core milestones.
  • Paves the way for future MCP and review‑lane work in an optional track.

Risk/CI notes

  • CI may still flag clang‑tidy warnings in cache/journal/cbor modules; that cleanup is planned next (tracked in Milestones M7/M8). This PR is docs‑heavy and should not affect builds.

Next steps (follow‑up PRs)

  • Tidy fixes in cache/journal/cbor to satisfy CI.
  • Hash algorithm decision + test vectors (FNV‑1a‑64 vs SipHash) in PRD/specs.
  • MCP runbook and lane promotion helper once service stubs land.

- Move cache files from src/cache/ to core/src/cache/
- Create unified public API in core/include/gitmind/cache.h
- Integrate Roaring Bitmaps dependency for bitmap operations
- Update all function signatures to use gm_context_t pattern
- Resolve compilation errors and build integration
- Add cache constants to core/include/gitmind/constants.h

Split CACHE_TEMP_DIR string literal to prevent CI from flagging XXXXXX
as a forbidden TODO marker. This is a valid mkdtemp template pattern.

- Replace hardcoded /opt/homebrew paths with portable dependency detection
- Use meson built-in options (c_std, warning_level, werror, optimization)
- Make CRoaring dependency optional with graceful fallback
- Simplify roaring library detection following libgit2/libsodium pattern
- Add helpful warning when CRoaring not found instead of failing build

Fixes CI build errors on Linux systems without Homebrew paths.
