PR Review: test(rivetkit): remove wasm sqlite-only fixtures and coverage

This PR cleanly removes ~1,200 lines of WASM SQLite test infrastructure as part of the shift to a native-only SQLite runtime. The intent is clear and the bulk of the deletions are straightforward. A few items worth addressing before merging.

Issues

1. Unnecessary try/catch in bench-sqlite.ts

The try/catch wrapping a plain console.log serves no purpose since console.log does not throw. This should just be a bare console.log call.

2. Delta-documenting comments in bench-sqlite.ts

CLAUDE.md says to avoid documenting what was there before. The comment "the old sqlite-native channel inspection path is gone" adds no value for a developer who never saw the old code. Either drop the comment or replace it with a forward-looking statement, e.g. Native database metrics are exposed via @rivetkit/rivetkit-native.

3. limits.mdx: clarify whether the SQLite preload limit still applies

The removed row documented Max SQLite preload size: 768 KiB and a configurable option options.preloadMaxSqliteBytes. If native SQLite no longer uses KV preloading at all (data stays on local disk), this deletion is correct. If the engine still preloads SQLite data to the runner at startup, the limit table should retain or replace this row with the native equivalent.

4. utils.ts formatting-only change

The only change in utils.ts is a multi-line reformat of a function call with no semantic effect. Looks like an incidental editor change worth reverting to keep the diff focused.

Minor

• ACTOR_KV_STRUCTURE.md: Removing the sqlite (8)/ namespace section is correct. Consider adding a one-line pointer to docs-internal/engine/NATIVE_SQLITE_DATA_CHANNEL.md so readers who land here know where the current SQLite data layout is documented.
• Test coverage: The removed actor-sleep-db.ts tested a "poisoned KV produces disk IO error on commit" scenario that reproduced a real production failure mode. If there is no equivalent test for how the native path surfaces IO errors to the actor runtime, worth tracking as a follow-up.

What is done well

• CLAUDE.md and rivetkit-typescript/CLAUDE.md updates are concise and correct: single bullet points, no paragraphs, forward-looking.
• All WASM-specific fixture actors, test files, and registry entries are consistently removed with no orphaned references left behind.
• The mod.ts cleanup correctly removes both the KV channel config setup and teardown alongside the removed test suites.
