Summary

This PR addresses naming inconsistencies, metadata errors, and correctness issues across the lexer codebase. Each change is a separate commit for easy review.

File Renaming

• nim_rename: Rename NimrodLexer → NimLexer, nim.py, add Nim 2.x keywords
• apdlexer: Rename apdlexer.py → apd.py, class apdlexer → ApdLexer (PEP 8)
• gcode_rename: Rename gcodelexer.py → gcode.py (remove 'lexer' from filename)
• inferno_rename: Rename inferno.py → limbo.py (file matches its content: LimboLexer)
• oberon_rename: Rename oberon.py → component_pascal.py (matches ComponentPascalLexer)
• dalvik_rename: Rename dalvik.py → smali.py (file matches its content: SmaliLexer)

Correctness Fixes

• dax_indent: dax.py: remove trailing tabs in inline comments (mixed indent)

Language Updates

• python_updates: python.py: StarlarkLexer, remove starlark/bazel from PythonLexer, add frozendict/sentinel builtins, add lazy keyword (PEP 690)
• css_modern: css.py: add @layer @container @Property @scope, oklch/oklab/color-mix, :has/:is/:where
• lua_refactor: Move Lua/Luau from scripting.py → lua.py, introduce _LuaBaseLexer

Testing

tox -e mapfiles   # regenerate _mapping.py
tox               # full test suite

Notes

• All file renames keep the original aliases intact for backwards compatibility.
• lazy keyword added for Python 3.15 (PEP 690).
• StarlarkLexer extracted from PythonLexer aliases into its own class.
• LuaLexer/LuauLexer moved to dedicated lua.py following the pattern of python.py, go.py, ruby.py, etc.
