fix(deploy): tolerate forge create progress noise when extracting addresses (#6)

`forge create --json` interleaves compile progress with the JSON payload on
stdout, so piping straight to `jq -r '.deployedTo'` breaks intermittently
(observed on the Stage 1b ERC1967Proxy deploy in a warm cache). Switch both
Stage 1a and Stage 1b extractions to grep the human-readable
"Deployed to: 0x…" line — stable across forge versions and cache states —
and validate the captured address before continuing so a malformed extract
can't silently propagate into ERC1967Proxy constructor args or the
`definition.json` manager patch.
