Three root defects in src/graph/traversal.ts (reported by @inth3shadows as #1086–#1090):
- Depth guard returned before visited.add → duplicate callers/callees at maxDepth=1 and getImpact loop disagreement.
- Dedup gate also gated edge collection → traverseBFS dropped a parallel edge; getImpact dropped a direct incoming dependency edge.
- limit checked per-frame not per-add → high-degree node overshot opts.limit in traverseBFS and dfsRecursive.
traverseBFS now collects every distinct edge among kept nodes (deduped on edge identity), enqueues each node once, and caps per-add. getCallers/getCallees/getImpactRecursive mark visited before the depth check; getImpactRecursive records the incoming edge unconditionally and unifies its loops on visited. 7 regression tests in graph.test.ts, each failing on the pre-fix code.

`callers <Class>` returned "No callers found" (or only the importing
file) even when a class's constructor was called from many sites, and
the instantiation sites were invisible — the opposite of what "what
breaks if I change this class?" should answer.
The `instantiates` edges already existed in the graph, correctly
attributed to the constructing function; they were simply excluded from
the caller/callee traversal, which queried only calls/references/imports.
Constructing a class is calling its constructor, so add `instantiates`
to the edge-kind set in both getCallers and getCallees (kept symmetric so
they stay inverses and `trace` can cross the instantiation boundary,
function -> class -> its methods). impact already traversed all edge
kinds, so it was unaffected.
Query-layer only — existing indexes benefit on upgrade with no re-index.
Verified on a Python fixture: `callers Supervisor` now returns the
construction sites (main/work/test_it), and a new graph test asserts
main() <-> DerivedClass via the instantiation. Full suite green.

Completes the cross-file dependency graph behind impact / affected / explore across all 22 supported languages and 14 web frameworks, validated on real-world repos (measured fair-coverage table added to the README). Per-language resolution + framework resolvers/synthesizers (Lua/Luau require, Shopify OS 2.0 Liquid sections, Delphi forms, Rust cross-module + Rocket macros, Swift Fluent, SvelteKit/Nuxt loader/component conventions, RN/Expo bridges). 0 cross-family false edges, full suite green (1187 passed). See #708.

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)
