chore: pin lance dependency to v6.0.0 for the v0.28 release branch

Re-targets the v0.28 release branch at lance 6.0.0 stable. Because
lance 6.0.0 directly uses object_store 0.12 while main has moved to
object_store 0.13, the change also reverts the object_store 0.13 port
from #3348:

* workspace `object_store` pin back to 0.12
* `rust/lancedb` aws feature no longer enables `object_store/aws`
* `MirroringObjectStore` and `IoTrackingStore` restored to the 0.12
  trait shape (overrides for `copy`, `delete`, `head`, etc. — no
  `copy_opts`/`rename_opts`/new `delete_stream` signature)
* `listing.rs`: `Path::clone().join(...)` → `Path::child(...)`
* `python/pyproject.toml`: `pylance>=6.0.0` (stable)
* `java/pom.xml`: `lance-core` 6.0.0
