Batch of small, localized fixes from an open-issue triage:
- .codegraph/.gitignore now ignores everything but itself, so the database,
daemon.pid, sockets, and logs stop showing up in git status (#492, #484)
- MCP server answers resources/list and prompts/list with empty lists instead
of -32601, clearing scary log lines in opencode/Codex (#621)
- index SAP HANA .xsjs/.xsjslib as JavaScript (#556) and TS .mts/.cts (#366)
- visit anonymous AMD/CommonJS/IIFE wrapper bodies so their inner functions and
calls are indexed instead of coming up empty (#528)
- batch the changed-file lookup so a huge first sync no longer hits
"too many SQL variables" (#540)
- list files with `git ls-files -z` so non-ASCII/CJK paths survive
core.quotepath and are no longer silently skipped (#541)
- attach Go methods on generic receivers (*T[P]) to their type (#583, RC1)
- impact no longer climbs the structural `contains` edge, so a leaf symbol
stops dragging in its sibling methods (#536)
- README: explicit `codegraph install` step, run in a new shell (#631)

One shared, detached daemon per project root: every `codegraph serve --mcp` is a thin stdio<->socket proxy (Unix socket / Windows named pipe) to it, so N agents in one repo share a single file watcher, SQLite connection, and tree-sitter warm-up instead of N copies. The daemon outlives any single session and reaps via client-refcount + idle timeout; `CODEGRAPH_NO_DAEMON=1` opts out.
Hardened during review: detached-process lifecycle (preserves the #277 watchdog via the proxy; the daemon no longer orphans on host SIGKILL), atomic lockfile + pid-verified stale-clear (no double-daemon on concurrent startup), realpath root canonicalization. Validated on macOS, Linux (Docker - 3x fewer inotify watches for 3 agents), and Windows (named pipes); A/B confirms byte-identical tool output vs direct mode. Closes#411.

The MCP `initialize` handler was awaiting `tryInitializeDefault` —
which opens the SQLite DB and runs `await initGrammars()` (tree-sitter
WASM bootstrap) — before sending the JSON-RPC response. On slow
filesystems (Docker Desktop VirtioFS on macOS, WSL2) this could exceed
Claude Code's ~30s handshake timeout, leaving the codegraph child
process alive and unresponsive with no tools visible in the client.
Send the response first; defer the open to a tracked background
promise. The lazy retry path used by `tools/list` and `tools/call`
now awaits that promise instead of racing it with `openSync`, so we
never double-open the SQLite file.
Adds a subprocess-based regression test that asserts the JSON-RPC
response arrives on stdout before `startWatching()` logs to stderr.
This ordering check catches the regression on any filesystem, not
just slow ones where the timing matters in practice.
