drift fix: validatord in start_go_stack + parity refresh

Browse Source 
Two anchor-vs-reality drifts found during /read-mem audit:

1. start_go_stack.sh never started validatord :3221, even though
   it shipped 2026-05-02 (f9e7241) and STATE_OF_PLAY claims it as
   part of the persistent stack. Cold-boot quietly omitted it,
   leaving /v1/iterate unreachable on the persistent gateway.
   Fix: factored chatd's conditional-start block into a start_shared
   helper, called for both chatd :3220 and validatord :3221. Same
   shared-with-smokes posture as chatd (no S3 / JSONL-only state,
   no temp-toml override needed).

2. STATE_OF_PLAY header claimed 3 parity probes / 32 assertions.
   Reality is 6 probes / 38 assertions since subject_audit landed
   in 262a77a (2026-05-03). Header refreshed; cross-references
   the three runtime-divergence classes documented at
   lakehouse/STATE_OF_PLAY.md lines 36-39.

Parity reports regenerated as verification artifact (all 6 still
green: 8+12+2+4+1+6). Same pattern as c0a55b1.
