Walkthrough

The PR updates the Ruff toolchain dependency from tag 0.15.5 to 0.15.6 with corresponding git revision updates and adds placeholder support for lazy imports by introducing new is_lazy fields in tokenization and AST statement handling.

Changes

Cohort / File(s)	Summary
Dependency Update `Cargo.toml`	Bumped Ruff toolchain from 0.15.5 to 0.15.6; updated four Ruff-related git dependencies (ruff_python_parser, ruff_python_ast, ruff_text_size, ruff_source_file) to commit e4c7f357777a2fdd34dbe6a98b1b7d3e7488f675.
Lazy Import Support `crates/stdlib/src/_tokenize.rs`, `crates/vm/src/stdlib/_ast/statement.rs`	Added placeholder support for lazy imports: new match arm for TokenKind::Lazy returning u8::MAX; added is_lazy field (bool) to StmtImport and StmtImportFrom AST nodes, both initialized to false.

Title check	✅ Passed	The pull request title 'Update ruff to `0.15.6`' directly aligns with the primary change in Cargo.toml, which bumps the Ruff toolchain from 0.15.5 to 0.15.6. However, the changeset also includes unrelated modifications to token handling and AST structures that are not reflected in the title.
