chore: disable snapshot compression with databend-meta v260628.2.0 (#20154)

* chore: disable snapshot compression with databend-meta v260629.0.0

# Summary

Disable snapshot compression by selecting databend-meta v260629.0.0 and its
uncompressed rotbl database, while pinning databend-meta-client to v260205.13.1.

# Details

This is a breaking dependency change: the selected meta release resolves rotbl
0.2.10 instead of the zstd-backed 0.3.0 release. Snapshot compatibility status
remains unchanged because V003 snapshot transmission has been dropped.

The update keeps the meta service test harness and supporting client crates on
their matching releases, so the resolved lockfile does not mix release lines.
