fix: No recovery path if VWAP bootstrap fails mid-sequence (#644)

Add recovery procedure documentation and automated recovery script for
when the VWAP bootstrap fails partway through (e.g. second recenter
reverts due to insufficient price movement).

- Add "Recovery from failed mid-sequence bootstrap" section to
  docs/mainnet-bootstrap.md with diagnosis steps and manual recovery
- Create scripts/recover-bootstrap.sh to automate diagnosis and retry
- Add warning comments in BootstrapVWAPPhase2.s.sol, DeployBase.sol,
  and bootstrap-common.sh referencing the recovery procedure
