fix: resolve all 8 Phase 3 config/path issues

V3.01-V3.03: Replace hardcoded Path.home() / 'Vault' with os.environ.get()
  - wiki_continuous_ingest.py: WIKI_ROOT via env with fallback
  - bulk_wiki_ingest.py: WIKI_ROOT + EMBEDDING_MODEL via env with fallback
  - backfill_decay_metadata.py: VAULT_ROOT via VAULT_PATH env with fallback

V3.04-V3.05: Replace hardcoded EMBEDDING_MODEL string with os.environ.get()
  - context_enhancer.py + bulk_wiki_ingest.py

V3.06: Replace ~/.hermes til fallback with ./hermes (Docker doesn't expand ~)

V3.07: Add /fabric volume mount (~/Vault/fabric:/fabric:rw)

V3.08: Add Qdrant healthcheck + change worker qdrant dependency from
  service_started to service_healthy
