It looks like there is an issue with the Tree-sitter grammar:

Error: failed to compile extension

Caused by:
    0: failed to compile grammar 'apex'
    1: failed to compile apex parser with clang: clang: error: no such file or directory: '/home/runner/work/extensions/extensions/extensions/apex/grammars/apex/src/parser.c'

It looks like the Apex Tree-sitter grammar keeps the grammar in a subdirectory: https://github.com/aheber/tree-sitter-sfapex/tree/943a3eb7f55733929ccafe06841087c3004cb4e0/apex

So you'll to specify that in the path under your grammar config in your extension.toml:

[grammars.apex]
repository = "https://github.com/aheber/tree-sitter-sfapex"
commit = "c99ad4b16d112fea91745e3f1b769754239fdaba"
path = "apex"

Thank you @maxdeviant, I added the path in this commit 👍🏻

Looks like there's a problem in one of the Tree-sitter queries:

[2024-10-08T16:17:21Z INFO  zed_extension] loaded grammar apex
Error: Query error at 13:4. Invalid node type list_initializer

I'm going to go ahead and close because there hasn't been any activity in a while. Happy to review a subsequent PR if you pick this up again in the future. Thanks.
