* Tiltfile: Make the guardian k8s_resource depend on solana-devnet
This makes guardian network convergence faster as the guardian pods
don't have to suffer from increasing redeploy back-off delays. This
should impact performance neglibibly as solana-devnet is still the
heaviest build we perform (at the time of this writing saturating a
32-thread Ryzen 9 CPU on my build machine.)
* hotfix bpf-sdk: bump bpf-sdk; use cargo-build-bpf
* upgrade solana sdk version
Commitment levels were deprecated and the fastest confirmation level is `Processed`.
Also the upgradeable loader now requires the program to be writeable.
* Add deprecation comment
* update agent commitment level
* bridge: add secp check instruction
* solana: update to secp solana upstream
* solana: iteration on secp
* solana: fix secp instruction
serialization indices were off and secp ix data was serialized twice
* solana: optimize ix serialization
* agent: send multiple chunks of signatures
* doc: update protocol spec
* solana: store signatures in siginfo; reconstruct signed VAA in webinterface
* solana: reformat
* solana: add rustfmt config
