fix(deps): update dependencies and fix all compilation errors

Updated dependencies to latest versions causing breaking changes:
- logos: 0.14 -> 0.16
- lalrpop: 0.21 -> 0.23
- thiserror: 1.0 -> 2.0
- petgraph: 0.6 -> 0.8
- notify: 6.0 -> 8
- toml: 0.8 -> 1.0.2
- tree-sitter (grammar): 0.20 -> 0.26

Fixed compilation issues:
1. logos 0.16: Added allow_greedy for unbounded repetitions in lexer
2. lalrpop 0.23: Changed from process_current_dir() to process()
3. tree-sitter 0.26: Updated bindings to use &Language reference

Also fixed Zed extension:
- Removed local highlights.scm override that had diverged from source
- Added regression test to prevent future divergence
