* feat(caching): embed every semantic cache prompt field except volatile ones
Replace the per-shape allowlist in the Python and Rust semantic cache prompt
walkers with one include-by-default walker. Plain text keeps its old
concatenation; any other block or message is embedded as compact JSON with
call ids mapped to ordinals, cache_control dropped, and signatures, encrypted
content and base64 data replaced with a short sha256 digest.

* refactor(rust): align the cache crates with Python and activate every backend
The cache port had drifted: lifecycle and Redis-only operations sat on
`BaseCache`, counters were pinned to `f64`, each semantic backend defined its
own embedder and prompt handling, and only the in-memory backend could be
selected natively.
- Split `disconnect` and `test_connection` out of `BaseCache` into optional
capabilities, implemented only where the Python class defines them, and give
every Redis-only operation its own capability trait.
- Decouple counters from the stored value type, so one backend can serve both
responses and counters as Python's `RedisCache` does.
- Share one `Embedder` and prompt contract in `litellm_cache::semantic`, and
make the Redis and Valkey semantic backends generic over their codec.
- Port the Python operations that were missing: `async_refresh_ttl`,
`async_rpush_and_trim`, `async_set_cache_pipeline_with_ttls`, the DualCache
pipeline, sadd, bulk delete and TTL reads, and the semantic-similarity
write-back.
- Take the HTTP client from the host pool in the GCS, S3 and Azure backends.
- Activate all nine backends through the Rust catalog, whose rules all stay
`PYTHON_ONLY`, and route the `Cache` facade's storage calls to the native
runtime when one is selected.
- Give every crate the same layout, move all tests to `tests/` on rstest, and
add the shared `litellm-cache-testing` contract suite.

* test(rust): opt the native Messages and tokenizer suites into Rust explicitly
#42517 made the Messages, token counter and tokenizer routes Python-only, so
tests/test_litellm_rust silently exercised the Python path or failed outright.
Each suite now prepends a RUST_OPT_IN rule for its route, keeping native
coverage without changing the shipped default.
