Lancedb updates (#1387)

`lancedb` no longer pulls `pylance` as a dependency, so we have to check
for it separately.

Also sneaks in an unrelated dependency fix in the spacy notebook.

Twelvelabs async file uploads (#1358)

Add `custom_metadata` and `comment` to add_computed_column() (#1343)

Dashboard performance and correctness fixes (#1308)

Performance

- /api/dirs: ~17.5s -> ~45ms on a 155-table catalog. Sidebar tree no
longer instantiates Tables (which triggers transformer model loads);
reads kind/version straight from the catalog.
- /api/pipeline gained a path query parameter that scopes to the
connected component. TableDetailView's per-table lineage fetch went from
~20s to ~85ms.
- Per-table error counts come from a single GROUP BY over tableversions
JSONB, not a per-table sweep.
- Data-table sort is restricted to B-tree-indexed columns. Avoids
unbounded sorts on Bool/JSON/unstored columns.

Correctness

- Views with unstored or iterator-output columns no longer break the
data tab. The bridge skips unstored columns from value/error fetches and
from sort, surfacing them as a muted placeholder in the UI.
- The pipeline endpoint no longer falls into the error-stub branch on
tables with unstored computed columns.

API

- New pxt.get_dir_tree() with TreeNode TypedDicts (DirectoryNode |
TableNode).
- TableMetadata gained id; IndexMetadata covers B-tree indexes too;
ColumnMetadata via the bridge gains is_stored / is_sorted.
- get_pipeline(tbl_path) for scoped lookups; error counts removed from
its response.

Frontend

- Sidebar/main and schema/data dividers are draggable
(react-resizable-panels), with persistence. Schema panel auto-fits on
first table visit, then remembers per-table.
- Schema column widths are drag-resizable with min-width clamps and
double-click reset.
- Long expressions open a click-to-expand modal with Python syntax
highlighting.
- All error-count UI is consolidated to the sidebar tree.
- Default B-tree indexes are filtered out of the schema-panel index
list.

Docstring formatting (#1305)

- Fix code block rendering bug in `doctools`
- Fix formatting errors in `_fastapi.py`
- Fix several related formatting errors elsewhere

PXT-1048 Expand Bedrock API to support media input and output (#1244)

- Add invoke_model_async with async context manager for S3 polling and
cleanup
- Add recursive media input conversion (_process_media_input) replacing
per-model field maps
- Add response image decoding for image-generation models (Stability,
Nova Canvas, Titan Image Generator)
- Add conditional_return_type for invoke_model_async (pxt.Video for Nova
Reel, Luma)
- Add Cohere embed v3/v4 support in embed UDF (text and image)
- Add Cohere embed-v4 image support via data URI encoding
- Add data URI input encoding for Mistral, Gemma, NVIDIA, Moonshot,
Qwen, Cohere embed-v4
- Add _apply_converse_request_conversions for automatic media-to-bytes
conversion in converse
- Expand _embedding_dimensions with Cohere models
