[marlon-costa-dc]

Summary

Updates tree-sitter from 0.25.x to 0.26.5 and all related grammar/build dependencies.

Dependency updates

Crate	From	To
tree-sitter	0.25.3	0.26.5
tree-sitter-javascript	—	0.25.0
tree-sitter-python	—	0.25.0
tree-sitter-rust	—	0.24.0
tree-sitter-kotlin	tree-sitter-kotlin-ng	tree-sitter-kotlin-codanna 0.3.9
askama	—	0.15

Code changes

• Node::child() API fix: tree-sitter 0.26 changed parameter from usize to u32 — updated child(pos) → child(pos as u32)
• Kotlin grammar macro: Added case for tree_sitter_kotlin_codanna::language() (function instead of LANGUAGE constant)
• Regenerated language enums: Updated all src/languages/ files for new grammar node types

Why tree-sitter-kotlin-codanna?

tree-sitter-kotlin-ng is no longer maintained. tree-sitter-kotlin-codanna (v0.3.9) provides active maintenance and tree-sitter 0.26 compatibility.

Test Plan

• cargo check passes
• All 251 existing tests pass (cargo test --workspace)
• Single clean commit rebased on upstream/master

@marlon-costa-dc the table in your PR description is missing the "From" version of some of the dependencies.

We’ve also lost the regeneration of the tree-sitter-mozcpp, tree-sitter-mozjs, tree-sitter-preproc, and tree-sitter-ccomment grammars that was previously included in #1214.
