v0.1.33

Fixed

• pyproject.toml — added missing tree-sitter-swift and tree-sitter-kotlin dependencies (CI workflows were failing to install them).
• CI workflows — added Rust toolchain setup for building tree-sitter-kotlin from source on Linux runners.
• visualize.py — guarded PermissionError in source code file lookup (was crashing on CI when scanning /tmp/ siblings).
• GitHub Pages deployment — fixed by resolving CI failures; docs/viz.html now auto-deploys.
