docs: use Enterprise terminology across website and SDK documentation (#4787)

Use “LanceDB Enterprise” throughout the staged website guides, SDK
reference sources, generated API pages, and user-facing SDK messages. A
separate branded “LanceDB Distributed” name adds terminology without
clarifying behavior; describe where operations run directly.

- Update `docs/web`, including the architecture diagram title and alt
text. Use Enterprise in headings, table labels, and prose; simplify
redundant product/execution-model wording and name the product only once
in the diagram alt text.
- Update Python docstrings and the Python/Java reference pages,
TypeScript comments and native declaration comments, and Rust API
documentation. Regenerate the TypeScript reference, including 24
replacements across six pages.
- Update SDK warnings/errors and existing test expectations to match,
along with contributor guidance and Vale rules. Remove the obsolete rule
distinguishing Enterprise from Distributed.
- Keep lowercase “distributed” for technical descriptions. API
identifiers, anchors, asset paths, and execution behavior are unchanged.
No branded-name exceptions are proposed.

Validation:
- Python and Node native builds succeeded; focused Python tests passed
(36 passed, 4 skipped), and focused Node tests passed (14).
- TypeDoc generation and the complete MkDocs reference build passed.
MkDocs retains an existing unresolved
`lancedb.functions.SecretReference` cross-reference.
- Rust formatting, Node lint/format, changed-file Python lint/format, 32
Vale tests, and whitespace checks passed. Repository-wide Python lint
has 48 existing findings in six untouched files.
- Combined documentation assembly passed. Mintlify validation and
link/anchor/redirect checks previously passed for both site builds; no
code snippets changed.
