Adds an `extra_ignore` option: .gitignore-syntax lines relative to the indexed root that take precedence over every ignore file. `!pattern` force-includes otherwise ignored paths (.env.local, logs, dotfiles repos ignoring `*`); plain lines exclude more. Closes the scan_inclusions request in dmtrKovalenko#719. - Lines feed zlob's `extra_ignore`, whose negations win over the project .gitignore/.ignore chain. The watcher reuses the walker's rules, so it stays consistent with no extra matching. The pure-Rust walker can't layer overrides and logs a warning instead. - When any `!` line is present, git status also reports ignored paths (dirs without recursion) so force-included files keep the `ignored` status and highlight. - Carried through rescans, restart_index and nvim directory changes. Bindings: nvim `extra_ignore`, FffCreateOptions v3 (newline-separated `extra_ignore`, struct 88 -> 96 bytes), node/bun `extraIgnore` (bun moves from v1 to v3 and now also passes followSymlinks), python `extra_ignore`, fff-mcp `--extra-ignore` (repeatable).

I'm not sure what does this function even do, we shouldn't loop all the files in the index on every status update

The change is fine with me, but what I think you missed is that zlob already exposes ignore rules that we use for basically anything, there shouldn't be needed any additional wiring to skip the files that are ignored, the watcher will already inherit the rules you pass to zlob
Filtering is fully handled by zlob's rules, which the watcher already reuses. The ignored-status wiring only labelled force-included files and looped the whole index on every git status update, so it is removed. Force-included files now report the regular (clean) git status.

128-129: 🎯 Functional Correctness | 🔵 Trivial | 🏗️ Heavy liftAdd an explicit watcher-batch completion signal before asserting exclusions.
shared_indexed(&shared, "secrets/new.env")proves only that the included file reached the index. Ignored paths are filtered before indexing, so their absence does not show that their events were processed. The test can miss a watcher regression that indexes an excluded path later.A sentinel file is not a deterministic barrier in this implementation. The watcher receives debounced batches, and the source exposes no guarantee that a later sentinel write completes all earlier batches. Add or use a watcher completion signal for the relevant event batch before checking the negative assertions.

@dmtrKovalenko You are right. To clarify, the git status bits weren't doing any filtering. That code only existed so force-included files would still show the git status (format_git_status) accurate to how git sees it. But its not clear if thats even desirable for all cases and I think definitely not worth it. Its removed now I also dropped the NUL filtering in zlob.rs that coderabbit had requested. Now if NUL is passed in extra_ignore it will warn which seems more correct to me than trying to quietly filter it. Thanks for your consideration! lmk if you have any further thoughts |
zlob rejects the whole list on an interior NUL, which also dropped IGNORED_DIRS on non-git roots (e.g. a home dir scan would walk node_modules). Fall back to the defaults alone.
