nix: support single-checkout and multi-workspace direnv setups 
The current `.envrc` unconditionally runs `use flake`, which breaks multi-workspace
jj setups where workspace subdirectories each have their own `.envrc`. Entering a
workspace unloads the root's nix env even when the workspace `.envrc` is blocked,
because direnv always unloads the parent env on any `.envrc` transition.

`source_up_if_exists` re-runs the parent `.envrc` and inherits its nix env in a
multi-workspace setup (fast due to caching). The `IN_NIX_SHELL` guard then skips
`use flake path:.`, which only runs in a plain single checkout where no parent
`.envrc` exists and `IN_NIX_SHELL` is unset.

Will Lillis 596a4d69bb fix(query): prevent cross-branch capture contamination in alternations with quantifiers 
When a branch inside an alternation has a + or * quantifier, the
quantifier's pass_through step loops back to the branch's first step.
The alternation linking also sets that step's alternative_index to
point to the next branch. This causes the quantifier loop-back to
incorrectly explore other branches in the case of a failed match that
follows a successful match, contaminating captures.

This is corrected by redirecting the quantifier loop-back to a
"clean" copy of the target step without the alternative index pointing
to the next alternation branch.

Jeremy Fleischman 7d3c321253 feat: allow - in grammar names 
A number of grammars in the wild have this character in their name:

- https://github.com/sogaiu/tree-sitter-janet-simple/pull/7
- https://github.com/tree-sitter/tree-sitter-c-sharp/pull/408
- https://github.com/tree-sitter/tree-sitter-embedded-template/pull/45
- https://github.com/tree-sitter/tree-sitter-ql-dbscheme/pull/7

I read through https://github.com/tree-sitter/tree-sitter/pull/3700 and
https://github.com/tree-sitter/tree-sitter/issues/3637, and it doesn't
look like there was much discussion about this name regex, so hopefully
this is an acceptable change?

Will Lillis 953e3f2630 fix(test): acquire lock before downloading wasm tools 
Because Rust tests run in parallel, two tests compiling a parser to wasm
can both try to download wasi-sdk and wasm-opt to a common location,
causing corrupted files and/or other failures. To prevent this, we can
guard access to these tools. `cfg(test)` isn't passed across crate
boundaries, so this lock must be present for all build configurations.

Will Lillis 337e20e0f2 fix(wasm): when reallocating the last allocated region, properly grow

Previous changes to `malloc` caused `realloc` to sometimes pull regions
off of the free list during this optimization. Because no `memcpy` is
performed, this resulted in corrupted data returning to the caller.

Will Lillis 439030503c fix(loader): don't rely on nm to verify scanner symbols 
Relying on a user's system's installation of `nm` has proven to be bug
prone and flaky. Instead, we can enforce that these symbols are defined
by requiring the linker to resolve them. This is already the default on
macos, but linux has looser requirements which defers the error to when
the library is opened. This check was not run on Windows (because
there's no `nm`), but the msvc linker is similiarly strict to macos's
w.r.t. resolving symbols at build time rather than runtime, so there's
no issue here.

Will Lillis 5177b3dc26 fix(lib): address strict aliasing violations with Array type 
Altering the `Array` type itself isn't feasible, as this causes
unacceptable breakage with existing parsers that depend on it. Instead,
pass in individual `Array` fields for to various `_array__*` functions.

Any time the `contents` of an array may be modified (`free`d, `realloc`d,
etc), return the potentially new address out by value. This prevents any
strict aliasing violations as we're no longer writing to a type-casted
pointer.
