The merger and executor verification gate (shared runVerificationCommand) used
a flat 10-min default (VERIFICATION_COMMAND_TIMEOUT_MS) for any configured
test/build command, while the fn_run_verification tool already derived its
default from command scope. A workspace-scoped command (a full suite, ~10+ min)
hit the flat 10-min wall and was killed as an infra timeout; a package-scoped
command got a too-generous bound.
Derive the default from command scope to match the tool: package-scoped
(pnpm --filter/-F ...) → 300s, workspace-scoped (root command like pnpm test)
→ 900s. An explicit project verificationCommandTimeoutMs still overrides, and
the 30-min hard cap still clamps the result. Covers both the merger and the
executor per-step auto-gate, which share runVerificationCommand.

Reorder backend/timeoutMsOverride params so timeoutMsOverride remains at
position 10 (matching callers in executor.ts, merger.ts from main).
Update mission-verification.ts call sites to pass undefined for
timeoutMsOverride before the isolating backend argument.
Non-TTY children spawned by the verification runner hung until the hard
timeout when Corepack prompted before fetching a pinned packageManager
version. Set COREPACK_ENABLE_DOWNLOAD_PROMPT=0 in the spawn env so the
fetch proceeds (or fails fast) without waiting on stdin.

Cleans up lint and type errors in the engine by removing unused imports from executor and merger, and replacing `any` types with proper type annotations in verification-utils.
