joakimp 113c9f0bb0 Infrastructure pass: CI smoke tests, floating versions, chown sentinel, generate-config script
Main changes:

- Extract opencode.json generation from entrypoint-user.sh into a
  standalone Python script (rootfs/usr/local/lib/opencode-devbox/
  generate-config.py). Preserves the never-overwrite-existing-config
  guarantee. Cuts entrypoint-user.sh from 176 to 97 lines.

- Install MemPalace via 'uv tool install' into an isolated venv at
  /opt/uv-tools/mempalace/ with a /usr/local/bin/mempalace-mcp-server
  wrapper, replacing the 'pip install --break-system-packages' escape
  hatch. The wrapper is what generate-config.py references in the
  auto-generated opencode.json. Also fix 'mempalace init' in
  entrypoint-user.sh to use --yes so first-start initialization isn't
  interactive (this used to hang or print prompts into the user's
  terminal). Gated by INSTALL_MEMPALACE build arg (default true) so
  users who don't need AI memory can shave ~300 MB.

- Sentinel-file pattern in entrypoint.sh volume-ownership loop: write
  .devbox-owner after a successful chown -R, skip the recursive walk
  on subsequent starts when the sentinel matches FINAL_UID:FINAL_GID.
  Cuts multi-second startup costs to milliseconds on large volumes
  (nvim plugins, palace data). UID changes still trigger a full chown.

- Float all GitHub/Gitea-hosted binary versions: gosu, fzf, git-lfs,
  neovim, bat, eza, zoxide, uv, gitea-mcp now default to 'latest' and
  resolve the newest upstream release at build time via the /releases/
  latest redirect. Go (go.dev JSON feed) and oh-my-opencode-slim (npm
  @latest) likewise. Intentional pins still in place: OPENCODE_VERSION,
  NODE_VERSION=22, DEBIAN_VERSION=trixie-slim. Each *_VERSION ARG
  accepts an explicit value to lock a specific version when needed.

- New scripts/smoke-test.sh verifies binary presence, opencode startup,
  entrypoint user drop, generate-config idempotency, bun's presence-
  per-variant, and image size against thresholds (2500 MB base, 3000
  MB OMOS). Prints resolved component versions as its first step so
  CI logs always record what got baked into a given image.

- New .gitea/workflows/validate.yml runs on push to main and PRs:
  single-arch amd64 build, smoke test, DOCKER_HUB.md sync check. Tag-
  triggered docker-publish.yml now smoke-tests each variant on amd64
  before the full multi-arch push.

- scripts/generate-dockerhub-md.py auto-generates DOCKER_HUB.md from
  README.md using explicit SECTION_RULES. --check mode fails CI when
  the committed file is out of sync. Enforces the 25 kB Docker Hub
  limit. Adding a new README section forces an explicit keep/drop/
  replace decision.

- Remove dead INSTALL_PYTHON build arg (was a no-op since mempalace
  added python3 unconditionally).

# Launcher for the MemPalace MCP server.
#
# MemPalace is installed via `uv tool install` into an isolated venv
# under /opt/uv-tools/. System python3 cannot import mempalace directly,
# so this wrapper exec's the venv's python with the mcp_server module.
#
# Used by opencode.json:
# "command": ["mempalace-mcp-server"]
