build(deps): Update tree-sitter to 0.26.3 and related dependencies

[marlon-costa-dc]

Summary

This PR updates tree-sitter from 0.25.x to 0.26.3 and updates all related grammar dependencies. It builds upon the work started in PR #1165 by @alexle0nte.

Dependency updates:

• tree-sitter: 0.25.3 → 0.26.3
• tree-sitter-kotlin: switched from tree-sitter-kotlin-ng to tree-sitter-kotlin-codanna 0.3.9
• tree-sitter-javascript: updated to 0.25.0
• tree-sitter-python: updated to 0.25.0
• tree-sitter-rust: updated to 0.24.0

Origin

Based on PR #1165 by @alexle0nte which updated tree-sitter to 0.25.4. This PR:

1. Takes that base and updates to tree-sitter 0.26.3
2. Switches Kotlin grammar to tree-sitter-kotlin-codanna (more actively maintained)
3. Fixes API compatibility issues introduced in tree-sitter 0.26

What it does

1. Updates all Cargo.toml files with new dependency versions
2. Regenerates language enum files in src/languages/ for updated grammars
3. Fixes tree-sitter 0.26 API changes:
   • Node::child() now requires u32 parameter (was usize)
4. Adds macro case for Kotlin grammar:
   • tree_sitter_kotlin_codanna::language() instead of ::LANGUAGE constant

Implementation decisions

Why tree-sitter-kotlin-codanna?

The previous tree-sitter-kotlin-ng crate is no longer maintained. tree-sitter-kotlin-codanna (v0.3.9) provides:

• Active maintenance
• tree-sitter 0.26 compatibility
• Uses language() function instead of LANGUAGE constant

API compatibility fix

Tree-sitter 0.26 changed Node::child(index) to require u32:

// Before (tree-sitter 0.25.x)
self.0.child(pos).map(Node)

// After (tree-sitter 0.26.x)
self.0.child(pos as u32).map(Node)

Macro changes

Added special case in get_language! macro for Kotlin:

(tree_sitter_kotlin_codanna) => {
    tree_sitter_kotlin_codanna::language().into()
};

• Revert "build(deps): Update tree-sitter to 0.26.3 and related dependencies" #1212 reverted a previous 0.26 attempt - this PR addresses those issues

Test plan

• All grammar crates compile successfully
• Main library compiles without errors
• Only warnings are pre-existing lifetime elision suggestions
• Run full test suite
