Validate decimal integer literals from the parser token stream before
lowering the parsed AST. Reuse the validator for normal compilation and
the `_ast` parsing path so `PyCF_ONLY_AST`, `ast.parse()`, and
`ast.literal_eval()` honor `int_max_str_digits` consistently.
Remove the now-passing `test_literal_eval_str_int_limit` expected-failure
marker. The token-based validator excludes non-decimal integers, floats,
complex literals, strings, and comments without duplicating lexer logic.

* Align compiler and AST behavior with CPython
Update the compiler pipeline, AST module support, and related VM compile/eval paths toward CPython 3.14 behavior.
Use upstream Ruff parser crates directly and keep RustPython-specific syntax preflight handling in the compile path.
Refresh opcode metadata, snapshots, and targeted tests for the aligned bytecode and AST behavior.
* fix
* Fix PR 8138 CI failures
* Fix match mapping wildcard scan complexity
* fixes
* Use Ruff runtime AST fields
* Minimize residual patch diff
* refactor error handling
* Remove _ast conversion context wrappers
* Clean up _ast conversion glue and compiler warning escalation
Rename the Node conversion parameter `ctx` to `vm` throughout the _ast
module.
Remove the unused compile_program, compile_program_single,
compile_block_expression, and compile_expression forwarders; compile_top
stays as the entry point.
Stash an escalated compiler SyntaxWarning so a non-SyntaxWarning category
propagates unchanged instead of being rewritten to SyntaxError, matching
PyErr_ExceptionMatches(SyntaxWarning) in compiler_warn. Drop the now-unused
CompileWarningError::into_codegen_error.
Replace the PositionalArguments two-variant enum with a struct holding a
shared range and a PositionalArgumentsKind enum.

* Represent compiler flags as a CompilerFlags bitflags
Replace the loose PY_CF_*/CO_* i32 constants in compile_mode with a
CompilerFlags bitflags covering the PyCF_* flags and __future__
CO_FUTURE_* bits. The Python-visible ast.PyCF_* attribute values are
derived from it via bits(); parser input modes stay plain consts.
builtins::compile and the compile_string flag handling test flags
through CompilerFlags::contains instead of raw bit math.

- frame.rs: compute the MATCH_CLASS class name lazily so a successful
match no longer takes the type name lock or allocates; the
__match_args__-not-a-tuple branch reuses it instead of recomputing.
- _ast/constant.rs: add the missing leading space to the with_recursion
label ("maximum recursion depth exceeded during compilation").
- sys.set_int_max_str_digits: restore the "maxdigits must be 0 or larger
than {n}" error text.
- codegen: set CO_MAXBLOCKS to 20 in both ir.rs and compile.rs.
- _ast/exception.rs: extract the duplicated excepthandler node guard
into ensure_excepthandler_node.
- codegen: correct the validate_keywords doc comment.
- Drop redundant "CPython" qualifiers from comments added in this branch.
