Four optional, serde-skipped-when-None fields added to `Metadata` for
code ingest context. All 11 downstream construction sites patched with
`repo: None, git_branch: None, git_commit: None, code_lang: None`.
Full workspace check (`--tests`) and per-crate test suite pass clean.

Add `DocumentStore::get_asset_by_workspace_path` trait method to
`kebab-core` and implement it on `SqliteStore` via a private
`asset_from_row` helper. Used by the incremental-ingest skip path to
compare a freshly-computed blake3 checksum against the persisted row
without a full round-trip through `put_asset_with_bytes`.

Add V006__incremental_ingest.sql to persist last_chunker_version and
last_embedding_version on the documents table. Wire both columns into
upsert_document (INSERT + ON CONFLICT UPDATE) and get_document (SELECT +
row mapper), replacing the previous hardcoded None. Add two round-trip
tests in tests/incremental_ingest.rs covering the set and None cases.
