Add docs/mainnet-bootstrap.md with the full two-phase bootstrap
sequence: pool init, 300 s TWAP warm-up wait, first recenter + seed
buy (exact cast commands), 60 s cooldown wait, second recenter via
BootstrapVWAPPhase2.s.sol, and verification/troubleshooting steps.
Update the inline bootstrap comment in DeployBase.sol to warn that the
attempt always reverts on a fresh pool and direct operators to the new
runbook.
