Code Review
This pull request adds documentation for numerous new geospatial and JSON functions, updates the geospatial overview to specify GEOMETRY/GEOGRAPHY support, and introduces a "Query Result Defaults" section to the worksheet guide. It also refines the STRIP_NULL_VALUE documentation. Feedback suggests using standard blockquote formatting for notes, applying backticks to technical terms like float32, and correcting minor grammatical inconsistencies for better alignment with the style guide.
Add documentation for the new SYSTEM$SET_CACHE_CAPACITY call and wire it into the TOC. Create tidb-cloud-lake/sql/set-cache-capacity.md describing syntax, notes, and examples. Expand system.caches doc (columns, cache list, example queries) to describe cache names, units, and usage; include note that disk_cache_column_data cannot be adjusted. Add Tag Operations sections to ALTER TABLE and ALTER VIEW docs (syntax and examples for SET/UNSET TAG). Also update an example ROLE_ARN value in alter-table.md.

Add documentation for unloading Lance datasets and table versioning (snapshot tags), and wire these features into the TOC and SQL reference. New pages: unload-lance-dataset.md, create-snapshot-tag.md, drop-snapshot-tag.md, fuse-tag.md, table-versioning.md. Update SQL pages to document LANCE as an unload-only FILE_FORMAT and COPY INTO <location> behavior (copy-into-location.md, create-file-format.md, input-output-file-formats.md), add AT(TAG) and snapshot-tag operations (at.md, alter-table.md), and expose the new table-versioning commands in the TOC. Also update Fuse Engine docs (fuse-engine-tables.md) with new options and version bump notes, fix a few links and small editorial/formatting issues (data-lifecycle.md, mcp-server.md, mindsdb.md, unload-csv-file.md, set-cache-capacity.md, tutorials/backup-restore-with-bendsave.md).
Add a new documentation page tidb-cloud-lake/guides/task-flow.md describing the Task Flow feature (concepts, tasks/flows, DAGs, creating/configuring flows, UI visualization, monitoring, runs/version history, scheduling, stream triggers, best practices, and permissions). Also update TOC-tidb-cloud-lake.md to include a link to the new Task Flow guide.
