npm is supposed to automatically install peer dependencies since v7
but sometimes it's not doing it and we need this dependency for tests
(cherry picked from commit e67f9f8f7a)
Currently, including a tree-sitter parser as a dependency in a zig
project and running `zig build test` on the project will fetch the
zig-tree-sitter dependency declared by the parser. This is a problem
because (a) consumers may not want this dependency for whatever reason
and (b) due to how often Zig breaks everything and how scarcely most
tree-sitter parsers are updated, the zig-tree-sitter version pinned
by the parser module will often be outdated and broken.
The workaround I used was taken from https://ziggit.dev/t/11234

Problem: When using alternations, the `#eq?` predicate does not always use the same capture name.
Solution: Iterate the left and right captured nodes more independently.
(cherry picked from commit 79177a1cd5)
Problem: When multiple input paths are provided to the `parse` command (a la `tree-sitter parse --paths [...]`), if a language can't be found for one of the paths, it can be a little unclear *which* path caused the failure. The loader *can* fail with `Failed to load language for file name <foo.bar>`, but this isn't guaranteed.
Solution: Attach some additional context in the case where multiple paths can be provided, displaying the problematic path on failure.

**Problem:** When encountering an invalid symbol at the beginning of the
file, the rust bindings attempt to index the character at position -1 of
the query source, which leads to an overflow and thus invalid character
index which causes a panic.
**Solution:** Bounds check the offset before performing the subtraction.

* Fix pkgconfig
Init CMAKE_INSTALL_INCLUDEDIR before pc file generation.
Install pc file to CMAKE_INSTALL_LIBDIR/pkgconfig -
it accompanies the architecture-dependent library.
* Include GNUInstallDirs early
The CMake module initializes variables which are used for
exported information (CMake and pkgconfig).
* Change pc file install destination

It is very common practice to ignore
these lock files for libraries, since they do not apply to applications
that use the libraries. The lock files are especially not useful in
tree-sitter grammar repos, since tree-sitter grammars should not have
dependencies. The lock files are just a source of merge conflicts and
spurious CI failures.
wasn't created.
This fixes an OOB access to `self.steps` when a last child anchor
immediately follows a predicate.

* Rename corpus test functions to allow easy filtering by language
* Use usize for seed argument
* Avoid retaining useless stack versions when reductions merge
We found this problem when debugging an infinite loop that happened
during error recovery when using the Zig grammar. The large number of
unnecessary paused stack versions were preventing the correct recovery
strategy from being tried.
* Fix leaked lookahead token when reduction results in a merged stack
* Enable running PHP tests in CI
* Fix possible infinite loop during error recovery at EOF
* Account for external scanner state changes when detecting changed ranges in subtrees

Instead of having users declare the extern function themselves, they can
pass in the language to `Language.create` in the zig bindings. If they
really want, they can always opt into the `extern fn tree_sitter_LANG()
*const ts.Language` approach.
**Problem:** When resetting the parser during subtree balancing, an
error is thrown:
```
parser.c:2198: ts_parser_parse: Assertion `self->finished_tree.ptr' failed.
```
**Solution:** Reset `canceled_balancing` to false in
`ts_parser_reset()`.
