Subject: [PATCH 1/3] feat: add lancedb 0.29.2 support

- Add constraints-0.29.2.txt with pyarrow>=16,<22
- Remove numpy<2.0 upper bound (0.29.2 supports numpy 2.x)
- Add 0.29.2 to CI build and test matrices
- Update latest/stable tags to point to 0.29.2
- Update Dockerfile default to 0.29.2

Subject: [PATCH 2/3] fix: restore numpy<2.0 default, override only for 0.29.2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Older lancedb versions (0.3.x–0.16.0) are incompatible with numpy 2.x.
Keep numpy<2.0 in requirements.txt as the safe default and add
numpy>=2.0 to the 0.29.2 constraint file instead.

Subject: [PATCH 3/3] fix: pin numpy<2.0 per-version in constraint files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pip constraints cannot widen requirements, so the numpy pin must
live in each constraint file rather than requirements.txt.
Old versions (0.3.1–0.24.3) get numpy<2.0; 0.29.2 has no numpy
constraint and picks up numpy 2.x naturally.
