Problem

Program account notifications are lossy and inconsistent because subscriptions specify a specific confirmation level and will only be notified when the RPC pubsub service observes a slot at that confirmation level where the account has been modified.

This is lossy for a number of reasons: async races, votes that include more than one block, slow consensus / network partitions.

Proposed Changes

TBD

Related to: #9833

bridge/pkg/solana: use polling GetProgramAccounts watcher (#156)
fd6c54d 
This mitigates solana-labs/solana#9909 by
polling GetProgramAccounts with a server-side filter. It also removes
the agent dependency for the lockup observation logic - the agent is now
used for transaction construction only.
