v1.0.0:3 — post-cutover seed strip

Removes the one-time `/data` snapshot from the deployed Docker image now
that the cutover from the legacy `workout-log` package is verified done
(v1.0.0:1 + :2 in production).

Dockerfile
- Drops `COPY start9/0.4/seed/data /app/seed/data`.
- Drops the `WORKOUT_BAKED_SEED_DB_PATH` env var.
- Comment block explains the rationale + how to re-seed if ever needed.

docker_entrypoint.sh
- Step 1 collapses to single-branch fallback: if /data is empty AND
  /app/prisma/data/app.db exists, copy the empty-schema fallback. The
  baked-seed branch is gone.
- Comment cross-references v1.0.0:3 for the rationale.

start9/0.4/seed/README.md rewritten to reflect historical-only status
+ how to re-seed for the rare "spin up another instance with this
history" case.

Version graph
- Adds startos/versions/v1.0.0.3.ts with empty up/down migrations and
  release notes.
- Promotes v1.0.0:3 to `current`; v1.0.0:1 and :2 move to `other` so
  hosts on either upgrade in place.

No schema changes, no data migration. /data on existing installs is
left exactly as-is. Image size drops by ~1.7MB (the snapshot size).

 # Responsibilities (in order):
 #   1. Ensure the persistent /data directory exists.
-#   2. Seed /data on truly-fresh first boot:
-#      a. If /app/seed/data/app.db is present (v1.0.0:1 cutover image),
-#         copy it into /data. This is how an operator migrating from
-#         the legacy `workout-log` package preserves their full history.
-#      b. Otherwise fall back to the empty-schema fallback DB at
-#         /app/prisma/data/app.db (already seeded with the curated
-#         exercise library at build time).
-#      Both branches are gated on /data/app.db being absent AND
-#      /data/.seeded being absent — never overwrites live data.
+#   2. First-boot fallback ONLY: if /data is empty (no app.db, no
+#      .seeded marker) AND a fallback DB exists at
+#      /app/prisma/data/app.db, copy it into /data. This handles
+#      brand-new sideloads on a host that has never had proof-of-work
+#      installed before. Existing installs ALWAYS skip this branch
+#      because /data/app.db is already present.
+#      (v1.0.0:1 had a second branch that copied a baked cutover seed
+#      from /app/seed/data/app.db. v1.0.0:3 stripped both the COPY of
+#      that seed in the Dockerfile and the branch that copied it here,
+#      now that the cutover from `workout-log` is verified done.)
 #   3. Run idempotent compat ALTERs for columns added after older snapshots.
 #      No-ops on hosts whose schema is already current.
 #   4. Ensure the curated exercise library is present for every user. New
