Add street-cred job unlock gating to job board. — The Last Job

Shipped as d1eb8de.

What Changed

This pass turns isolated demo runs into campaign play by preserving state, gating jobs through reputation, and showing the player what changed after each run.

Worked in job board and contract flow.
Worked in test coverage.

Why It Matters

Campaign continuity gives the player a reason to care about each run beyond a single random result.
