Python evaluator. Now properly specced and available in both hosts.
Removes mock injections from cache tests — they use real primitives.

- 10 new tests: cache key generation, set/get, TTL expiry, overwrite,
key independence, complex nested data
- Update data-test.sx with cache verification instructions:
navigate away+back within 30s → client+cache, after 30s → new fetch

Tests cover: SX wire format roundtrip for data dicts (11 tests),
kebab-case key conversion (4 tests), component dep computation for
:data pages (2 tests), and full pipeline simulation — serialize on
server, parse on client, merge into env, eval content (3 tests).
