Replaces the old Claude-only CLAUDE.md with a comprehensive guide covering
the full project architecture, multi-agent installer, test conventions,
NodeKind/EdgeKind reference, and release workflow. Key additions:
- Documents the layered pipeline, all module paths, and the multi-target
installer (targets/, registry.ts, AgentTarget interface).
- Adds the Cursor `--path` quirk and the "update all three surfaces" rule
when changing MCP tool guidance.
- Documents `npm run eval`, `test:eval`, and the full set of build/test
commands including single-file patterns.
- `scripts/release.sh` — idempotent bash script that tags the current
commit, pushes the tag, and creates a GitHub Release whose notes are
extracted from the matching `## [X.Y.Z]` block in CHANGELOG.md. Safe
to re-run after partial failure.
- `.cursor/rules/codegraph.mdc` — Cursor-specific agent instructions
(tool decision table, rules of thumb, index-lag warning) written by
the installer and kept in sync with server-instructions.ts and
instructions-template.ts.
