* feat(rust): add python-compat crate for Python data formats
Add litellm-python-compat, a PyO3-free crate that reproduces the Python
data formats LiteLLM persists, so Rust readers and writers can interoperate
with state written by the Python proxy:
- literal::literal_eval: a linear recursive-descent port of
ast.literal_eval (prefixes, escapes, implicit concatenation, numeric
underscores and radixes, single unary sign, real +/- complex with 3.14
mixed-mode rules, set(), Python-equality key dedup)
- repr::{repr, to_str}: byte-exact repr()/str(), with a printable table
generated from CPython's str.isprintable (Unicode 16.0.0)
- json::{dumps, from_json, to_json}: json.dumps defaults and the
json.loads mapping
- pickle::{loads, dumps}: plain-data pickles via serde-pickle's serde
interface, which keeps dict insertion order
- truthy::truthy: bool() for plain data
Tests replay fixtures generated by CPython 3.14 (values across every
format and pickle protocol 0-5, plus 154 literal_eval source texts).
Accepted divergences are pinned in a KNOWN table that fails once one
starts matching. A criterion bench covers each format and literal_eval
cost by nesting depth, guarding the linear parse: the py_literal grammar
doubled per nested bracket (105 ms at 16 nested dicts; 19 us at 128 now).

* refactor(rust): split python-compat modules and harden the pickle verifier
- Disable class resolution in scripts/verify_rust_pickles.py, and truncate
the export file once instead of removing and appending to it, so the
verifier cannot be pointed at a pre-created file whose rows execute code
through pickle.loads
- Move Error to error.rs and Value to value.rs, leaving lib.rs as the crate
overview, module list and MAX_DEPTH
- Move the generator and verifier to scripts/, beside the Unicode table
generator, leaving tests/ to the Rust tests
- Group the bench by measured surface, give every case a Throughput so
criterion reports bytes per second, and document baseline comparison
