release(catalog): pin Bitcoin Knots to 29.3.knots20260210 — signed

Moves the default off 29.3.knots20260508, which applies the BIP110/RDTS
network upgrade and HALTS until an operator sets consensusrules=rdts. A node
running it sits frozen — 100.64.204.114 is stuck at block 961,692 with blocks
AND headers static, 11 peers and no pruning, while reporting
initialblockdownload=false and verificationprogress 0.99998, i.e. "synced".
The nodes on 20260210 are at the tip.

The old catalog's default was {"version":"latest", image: ...20260508} while
the manifest's :latest tag resolves to 20260210 in the registry, so a fresh
install and a plain pull produced different daemons. That is almost certainly
how one node ended up on the RDTS build and its siblings did not.

20260508 stays selectable — adopting RDTS remains possible, just deliberate.

Diff against the previously-signed catalog is exactly one app, all four
fields: version, image, default and the embedded manifest. Registry hosts
unchanged and inside the trust floor; verified by
check-catalog-registry-trust.py and `ceremony verify`.
