grammars must have a file src/parser.c (i.e. cannot link against system-shared tree-sitter library)

Discussed in #7200

Summary

helix-loader grammar compiler supports grammars that omit src/scanner.c but fail to compile if src/parser.c is missing.

Reproduction Steps

I tried switching to the alternative Perl grammar in languages.toml:

[[grammar]]
name = "perl"
source = { git = "https://github.com/tree-sitter-perl/tree-sitter-perl", rev = "7dab73715fa18309102892eda2b190bcb3c7b9b4" }

hx --grammar fetch succeeded, but hx --grammar build failed.

Patching helix to tolerate missing parser.c makes the build succeed, (and the resulting experience is a more reliable Perl grammar - I'll file a separate issue about that see #7201).

I now spotted that I had locally overriden my derived built-in source URI back to the original one: My patch makes the build succeed but the resulting code does not present any color highlighting. Sigh.

Closing as a non-bug.
