v0.9.75

Intra-class call binding across five languages, new language-structure coverage, and a batch of resolution/build/cache fixes.
- Feature: `self`/`this`/`super` member calls now bind to the caller's own class chain instead of the file-wide last-definition, across **Python** (`self.`/`cls.`/`super()`, nearest ancestor in the in-file MRO) (#4011), **JavaScript/TypeScript** (`this.m()` to the caller's own class; `super.m()` fails closed since the `extends` chain is not known at that pass) (#4012), **Swift** (`self`/`super`, class vs struct/extension aware) (#4030), and **Ruby** (`self`-sends within the class chain, complementing the paren-less self-send extraction from 0.9.74) (#4031) — all thanks @Cintu07. Multiple-inheritance ties and unknown/external ancestors fail closed (no fabricated edge).
- Feature: four more language extractors gained structural coverage from @rajatnagda45 — **Zig** error-set declarations and their members (`case_of`) (#4025), **PHP** enum cases (pure and backed) with `case_of` edges (#4026), **Elixir** `defmacro`/`defmacrop`/`defguard`/`defguardp` definitions (#4027), and **Rust** `macro_rules!` definitions with local invocation resolution (std macros like `println!` fail closed, no fabrication) (#4028).
- Feature: three **Scala** type-reference fixes from @Faisal-Fayaz — file-scope `val`/`var` type annotations now emit `references` edges (#4036, #2054), `type` alias/definition right-hand sides are walked (including `opaque type` and match types) (#4037, #2049), and context bounds (`def f[A: Ordering]`) resolve to `references` edges (#4038, #2046).
- Feature: single-implementer interface dispatch was lifted into a language-agnostic core (#4034) and reused to dispatch a **Swift** protocol requirement to its sole conformer (INFERRED), failing closed on 2+ conformers (#4035) — thanks @GAURAV-1313.
- Feature: **Elixir** unqualified calls now resolve to functions brought in by `import`/`use`, scoped per module and fail-closed when no in-scope module defines the name (fixes a large god-node from corpus-wide bare-name binding) (#4015, thanks @Ayushraj06-bit).
- Feature: a **bash** script's invocation of another script through a non-shell interpreter (`python3 build.py`, `node build.js`, `"$PYTHON" stage.py`) is now recorded as an `invokes` edge; a `$VAR`/path command word is not mistaken for an interpreter (#4007, thanks @ayushcodes10).
- Feature: **Dart** `part` files keep their own file node linked to the library (#4013, #4008), and a configurable import/export (`import 'a.dart' if (...) 'b.dart';`) now links every URI branch, not just the default (#4003, #4002) — thanks @brlumen.
- Fix: C# partial-class merging no longer drops recursive/intra-class `calls` edges; one split `partial class` anywhere in a repo used to erase every recursive self-loop graph-wide (#4017, thanks @rohit-jsfreaky).
- Fix: `graphify path` (CLI and the MCP `shortest_path` tool) now routes through a `contains` edge back out to a symbol's file, so a cross-file dependency that must pass through a shared symbol is found instead of reporting no path (#4004, #3878, thanks @ayushcodes10).
- Fix: the AST cache rebinds its stat index when a later call names a different cache root, so a multi-project process writes each root's `stat-index.json` with only its own files instead of pooling them into the first root's file (#4005, #3989, thanks @ayushcodes10).
- Fix: `merge-graphs --previous <merged-graph.json>` restores the previous merged community assignment by node id, so cluster/label reuse stays stable across re-merges; a malformed `--previous` file now errors cleanly instead of crashing (#4006, #3858, thanks @ayushcodes10).
- Fix: `cluster-only`/`label` no longer drop parallel edges (two different relations between the same pair) when reloading and rewriting a graph; preserved links track node-id remaps so none are silently dropped on a legacy graph (#4010, #3999, thanks @ayushcodes10).
- Fix: the Ollama `num_ctx` setting is merged into `extra_body` instead of replacing it, so a `GRAPHIFY_DISABLE_THINKING` body set on the same backend is no longer silently clobbered (#4029, #3988, thanks @Agnik47).
- Fix: the hook-guard reminder names the effective `graph.json` path when `GRAPHIFY_OUT` is customized, instead of always naming the default `graphify-out/graph.json` (#4042, #4040, thanks @DeepanshuPal).
- Fix: `graphify extract` refuses to overwrite an existing graph with a dedup-shrunk one unless `--allow-dedup-shrink` is passed; the refusal reports the actual number of nodes dedup merged (#4014, #3774, thanks @SrijanSriv).
- Feature: extraction warns once when a cleanly-parsed code file yields no symbols beyond its own file node (often a data literal), while staying silent on empty/whitespace-only files, no-extractor languages, and intentionally-skipped data (#4009, #3946, thanks @ayushcodes10).
