Initial import — snapshot from admin host /srv/gosec/gsc-ops-api

This repo had no version control prior to this commit. The import is a
straight snapshot of the working tree at 2026-05-03; the deployed
binary on fihelvop01 was being rebuilt from this source via `make
build` + scp into place, with no upstream review path.

The snapshot already includes one in-flight fix made on 2026-05-03 to
internal/service/persona.go:GetSelfModel — the handler queried
`source` and `strength` columns plus an `is_active = true` filter on
persona.persona_commitments, none of which exist on that table (its
shape is session-bound commitments with `status`, `commitment_meta`,
etc.). The query returned a 500 every time SynapseHub bootstrapped a
persona's self-model, dropping the IdentityConstraints / Commitments /
ConscienceStandards layer from the assembled prompt. The patched
query reads existing columns only (commitment_text, commitment_type),
filters on `status='active'`, and synthesises Source="learned" /
Strength=1.0 to keep the SelfModel response shape stable for callers.

Verified live: `GET /api/v1/personas/70f7cfd9-.../self-model` now
returns 200 with `{identityConstraints:[],commitments:[],
conscienceStandards:[]}` instead of 500.

Future changes go through PRs against this repo — no more bin-only
deploys.
