The WASM reader and the shared writer (Workers) now read and write Iceberg manifests, manifest lists and table metadata through lakekit (D24, spec 13), which lakeglass will use too. lakekit is merged (polythings/lakekit#8, #9, #12) and builds on loko (polythings/loko#5, merged) for its store, clock, and random services; the WASM writer takes the time and random numbers from loko's JsClock and JsRandom.

• timelake-format: host re-exports lakekit's Host plus a WriteHost trait for the two writer limits; commit runs lakekit's commit with Timelake's parts as CommitHooks (last-value index, batch ids, rollup provenance, head-first reloads); FileStats wraps lakekit's ParquetStats with the footer; a file's time partition maps to lakekit's typed partition tuple (time_partition, partition_values).
• timelake-wasm: manifests read by lakekit instead of its own Avro code; the JS host implements lakekit's traits. Bundle rebuilt (+0.6%).
• Engine: unchanged except FileStats access; its manifest-equivalence unit test moved to lakekit, whose interop test runs iceberg-rust and lakekit on one table in turn. tests/shared_writer.rs still checks the engine and the shared writer on one table.
• Fixed: a JavaScript writer whose clock is behind the table's last update dates its commit at that update, so iceberg-rust can load the table.

Dependencies: lakekit 0.1 and loko 0.2 come from crates.io (published 2026-10-22), with no git sources, so timelake-format can be published (cargo publish --dry-run -p timelake-format passes).

Checks: clippy (workspace and wasm32) and rustfmt clean; cargo test --workspace and the WASM crate's tests pass; the bundle matches its sources; the spec index is current. ty and bench queries failed locally only because they ran with the main checkout's virtualenv (an editable timebench from a newer checkout); no Python changed.
