Gate: is sift initialized?

Run sift-init's scripts/sift-gate.sh first. Use its resolved root and exit code:

• 0 (READY). Continue below.
• 3 (UNINITIALIZED). Hand off to sift-init; initialize without asking.
• 4 (UNINITIALIZED). Hand off to sift-init; report the resolved path and ask before initialization.
• 6 (INCOMPLETE). Hand off to sift-init; repair without asking.
• 5 (UNRESOLVED). No project root found. Report the $PWD it walked from and stop.

tests/static/gate-handoff-contract.test.sh checks these handoffs.
