Add extraIgnore, disableGit, and disableIgnoreFiles to the Node and Bun SDKs. disableGit skips Git integration and .gitignore rules, and disableIgnoreFiles independently skips .ignore rules. FffCreateOptions version 3 appends fields for all three settings.

FileFinder.create({
  basePath: process.cwd(),
  extraIgnore: ["/generated/"],
  disableGit: true,
  disableIgnoreFiles: true,
});

Refs #530.

Closes #898 (comment)

Uses the zlob version from the workspace. disableGit also turns off info/exclude and core.excludesFile.

Summary by CodeRabbit

• New Features
  • Added configurable extra ignore patterns, including ! patterns to re-include matching paths.
  • Added options to disable Git integration and Git-based or .ignore-file rules independently. These settings apply across scans and filesystem updates.
  • Documented the new settings for Node and Bun SDKs; they require a zlob build.

Walkthrough

Node, Bun, and C APIs add options for extra ignore rules and disabling Git or .ignore handling. The picker applies these settings to scans and watcher updates, and restart operations retain them. The C options structure advances to version 3.

Changes: Configurable ignore behavior

Layer / File(s)	Summary
Options and C ABI packages/shared/fff-api.ts, packages/fff-node/src/fff-api.ts, packages/fff-bun/src/fff-api.ts, crates/fff-c/include/fff.h, crates/fff-c/src/ffi_types.rs, crates/fff-c/cbindgen.toml	SDK options and the C options structure add extra ignore rules and switches to disable Git and .ignore handling. The C options version advances to 3, with compatibility handling for older layouts.
SDK and picker initialization packages/fff-node/src/ffi.ts, packages/fff-bun/src/ffi.ts, packages/fff-node/src/finder.ts, packages/fff-bun/src/finder.ts, crates/fff-c/src/lib.rs, crates/fff-c/include/fff.h, crates/fff-c/tests/smoke.c, crates/fff-core/src/file_picker.rs	The SDKs encode and pass the options to native creation. The C API parses the options and initializes the picker with them. Picker restarts preserve the current ignore settings.
Scan and walker behavior crates/fff-core/src/file_picker.rs, crates/fff-core/src/scan.rs, crates/fff-core/src/walk/*, crates/fff-core/src/watcher/rescan_tests.rs	Scans pass ignore options to filesystem walks. The zlob walker applies the disable switches, combines extra rules with defaults, and supports scoped traversal.
Watcher behavior and tests crates/fff-core/src/watcher/background_watcher.rs, packages/fff-node/test/watch.mjs, packages/fff-bun/test/index.test.ts, README.md	Watcher event filtering and new-directory indexing use the configured ignore settings. Tests cover scan and watcher behavior; the README describes the options and rule syntax.

Full details: Title check

Explanation

Title names the main change: ignore-rule configuration (extraIgnore, disableGit, disableIgnoreFiles) for the Node/Bun SDKs and the underlying C/core changes, so it matches the changeset. It is concise and follows the conventional-commit style. Scope 'sdk' is slightly narrow because the diff also changes the C FFI and fff-core, but the title still points at the primary change.

Full details: Docstring Coverage

Explanation

Docstring coverage is 28.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 25 functions across 20 files. (2 skipped: 2 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.
