### Purpose
<!-- Linking this pull request to the issue -->
Rust already supports reading Lumina global indexes, but it did not have a
core path to build Lumina index files from table data and commit them into the
index manifest. Index-only commits were also skipped, so the generated index
metadata could not create a new snapshot.
<!-- What is the purpose of the change -->
### Brief change log
<!-- Please describe the changes made in this pull request and explain how
they address the issue -->
- Add `LuminaIndexBuildBuilder` on `Table`.
- Plan Lumina shards by global row id and
`global-index.row-count-per-shard`.
- Extract `ARRAY<FLOAT>` vectors with strict `_ROW_ID` continuity
validation.
- Build Lumina index files under `index/lumina-global-index-*.index`.
- Commit Lumina `IndexFileMeta` with canonical `index_type = "lumina"` and
global row range metadata.
- Support metadata-only index commits and reject overlapping global index
ranges.
- Fail fast for unsupported primary-key and deletion-vector tables.
### Tests
