Sync with tree-sitter-typescript v0.23.0

[Copilot]

This fork extends tree-sitter-typescript to add <template> tag syntax for Glimmer templates. The relevant upstream files (grammar definitions and scanner) had not been synced since the initial fork.

Changes

• Added upstream files to src/tree-sitter-typescript/ from tree-sitter-typescript v0.23.0:

  • define-grammar.js - Core TypeScript grammar factory (1147 lines)
  • scanner.h - Lexical scanner definitions (347 lines) - updated to match upstream

• Added ESLint v9 configuration (eslint.config.mjs) using eslint-config-treesitter to fix previously broken lint script

The Glimmer-specific extensions in grammar.js remain unchanged and continue to extend the base TypeScript grammar:

const TypeScript = require("tree-sitter-typescript/typescript/grammar");

module.exports = grammar(TypeScript, {
  name: "glimmer_typescript",
  rules: {
    glimmer_template: ($) => seq(/*...*/),
    expression: ($, previous) => choice($.glimmer_template, /*...*/),
    class_body: ($) => seq(/*... with glimmer_template support ...*/),
  },
});

@copilot has this not changed since 0.23.0?

[Copilot]

Confirmed - the scanner.h content is identical to v0.23.0 and also matches the current upstream v0.23.2. I only removed the version comment header; the actual code hasn't changed in upstream since v0.23.0.

@copilot files from tree-sitter-typescript should go in the src/tree-sitter-typescript folder

[Copilot]

Done in af9c736 - moved define-grammar.js and scanner.h to src/tree-sitter-typescript/ and updated the lint script accordingly.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/tree-sitter/tree-sitter-typescript/releases
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)
• https://api.github.com/repos/tree-sitter/tree-sitter-typescript/releases/latest
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
