Subject: [PATCH] fix: add missing stacklevel=2 to warnings.warn() calls (Fixes
 #3589) (#3590)

Fixes #3589

## Problem
Multiple `warnings.warn()` calls across the Python client are missing
the `stacklevel=2` parameter. This causes warning messages to point to
lancedb internal code instead of the user's code that triggered the
warning, making debugging difficult.

## Solution
Add `stacklevel=2` to 7 `warnings.warn()` calls across 4 files:

| File | Warnings Fixed |
|------|---------------|
| `remote/db.py` | `request_thread_pool`, `connection_timeout`,
`read_timeout` deprecation warnings |
| `remote/table.py` | `cleanup_old_versions`, `compact_files`,
`optimize` no-op warnings |
| `table.py` | `data_storage_version`, `enable_v2_manifest_paths`,
`retrain` deprecation warnings |
| `embeddings/colpali.py` | `use_token_pooling` deprecation warning |

## Verification
- All 4 modified files pass `ast.parse()` syntax check
- Only `stacklevel=2` added — no other changes

## Changelog
