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.

**Problem:** `query.c` compares the current analysis state with the
previous analysis state to see if they are equal, so that it can return
early if so. This prevents redundant work. However, the comparison
function here differs from the one used for sorted insertion/lookup in
that it does not check any state data other than the child index. This
is problematic because it leads to infinite analysis when hidden nodes
have cycles.
**Solution:** Remove the custom comparison function, and apply the
insertion/lookup comparison function in place of it.
**NOTE:** This commit also changes the comparison function slightly, so
that some comparisons are reordered. Namely, for performance, it returns
early if the lhs depth is less than the rhs depth. Is this acceptable?
Tests still pass and nothing hangs in my testing, but it still seems
sketchy. Returning early if the lhs depth is greater than the rhs depth
does seem to make query analysis hang, weirdly enough... Keeping the
depth checks at the end of the loop also works, but it introduces a
noticeable performance regression (for queries that otherwise wouldn't
have had analysis cycles, of course).

**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

wasn't created.
This fixes an OOB access to `self.steps` when a last child anchor
immediately follows a predicate.
(cherry picked from commit b1d2b7cfb8)
This fix allows for more granular address control when marshalling nodes
across WASM. This is necessary for node methods which accept another
node as a parameter (i.e., `childWithDescendant()`)
(cherry picked from commit 21390af2dd)
**Problem:** After `ts_parser_parse_with_options()`, the parser options
are still stored in the parser object, meaning that a successive call to
`ts_parser_parse()` will actually behave like
`ts_parser_parse_with_options()`, which is not obvious and can have
unintended consequences.
**Solution:** Reset to empty options state after
`ts_parser_parse_with_options()`.

* 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

When using TypeScript projects using other module settings than CommonJs, the types were not correctly exposed, and the compilation failed.
This adds the types path to the exports so compilation works for `module: NodeNext` and other variants.

**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()`.
