feat: wire circuitforge-core config.load_env at entry points (closes #68 partial)

- app/app.py: load_env at module level (safe in Docker, fills gaps on bare-metal)
- dev_api.py: load_env in startup handler (avoids test-env pollution)
- requirements.txt: note >= 0.7.0 requirement; TODO tag once cf-core cuts release

db.migration runner deferral: tracked in #43 (Rails-style numbered migrations)
CFOrchClient VRAM wiring: already present in task_scheduler via CF_ORCH_URL env var

 # ── CircuitForge shared core ───────────────────────────────────────────────
+# Requires circuitforge-core >= 0.7.0 (config.load_env, db, tasks, resources).
 # Local dev / Docker (parent-context build): path install works because
 # circuitforge-core/ is a sibling directory.
 # CI / fresh checkouts: falls back to the Forgejo VCS URL below.
 # To use local editable install run: pip install -e ../circuitforge-core
+# TODO: pin to @v0.7.0 tag once cf-core cuts a release tag.
