Bump opencode to 1.14.30

The mempalace Python package ships a 'mempalace-mcp' console entry
point; 'uv tool install' places it on PATH as a shim whose shebang
points at the isolated venv's Python. Our hand-rolled wrapper at
/usr/local/bin/mempalace-mcp-server was duplicating what uv installs
for free — one less file to maintain.

Fixes the MCP error users saw after the v1.14.28b → v1.14.29 upgrade
path: custom opencode.json files typically had the pre-v1.14.29
command ['python3', '-m', 'mempalace.mcp_server'] which worked with
the old pip install but fails silently after the uv-tool migration
because system python3 cannot import from the venv. Opencode surfaced
this as 'MCP error -32000: connection closed'.

- generate-config.py now emits ['mempalace-mcp'] and keys its detect
  on shutil.which('mempalace-mcp').
- Dockerfile drops 'COPY rootfs/usr/local/bin/' and the chmod of the
  wrapper. Build shrinks from 30 to 29 stages.
- rootfs/usr/local/bin/ removed entirely.
- Smoke test asserts /usr/local/bin/mempalace-mcp is executable and
  prints its symlink target.
- README's MemPalace section shows ['mempalace-mcp'] and explicitly
  warns against the old pattern with the observed failure mode.
- CHANGELOG adds a v1.14.29c entry.

 - **GitHub/Gitea-sourced binaries float by default** — gosu, fzf, git-lfs, nvim, bat, eza, zoxide, uv, gitea-mcp, Go, oh-my-opencode-slim all default to `latest`. Each build-time install step reads the `/releases/latest` Location redirect (or the go.dev JSON feed for Go) and derives the concrete version. Use the same `ARCH` case-switch pattern for multi-arch support (amd64/arm64). Intentional pins: `OPENCODE_VERSION` (drives the image tag), `NODE_VERSION=22` (major pin), `DEBIAN_VERSION=trixie-slim` (OS base). Adding a new upstream tool: follow the existing floated-version pattern, don't hardcode a specific tag.

+- **MemPalace install path** — installed via `uv tool install` into `/opt/uv-tools/mempalace/`.

No hand-rolled wrapper is needed. Do not use `pip install --break-system-packages` — that was the previous approach and has been removed. Do not use `["python3", "-m", "mempalace.mcp_server"]` in `opencode.json` — system Python can't import from the uv venv.
 - **generate-config.py idempotency** — the script MUST never overwrite an existing `opencode.json`. Users bind-mount their config directory or persist it across container recreations; accidentally clobbering that file would destroy hand-edits. The smoke test asserts this.

+
+**Drop redundant mempalace-mcp-server wrapper, use the entry point mempalace ships.**
+
+- **Fix:** MCP integration with mempalace was still broken for users with custom `opencode.json` files because they typically had `["python3", "-m", "mempalace.mcp_server"]` from v1.14.28b and earlier. With the uv-tool install path, system python3 can't import mempalace and the MCP server subprocess exits immediately — opencode surfaced this as `MCP error -32000: connection closed`. Users should migrate to `["mempalace-mcp"]`. The auto-generated config in new containers already emits the new form.
+- **Cleanup:** Remove the hand-rolled `/usr/local/bin/mempalace-mcp-server` wrapper. The mempalace Python package ships a `mempalace-mcp` console entry point; `uv tool install` places it on PATH as a shim whose shebang points at the isolated venv's Python. The wrapper was duplicating what uv installs for free. Removed `rootfs/usr/local/bin/` and its COPY + chmod lines from the Dockerfile.

+
+## v1.14.29b — 2026-04-29
+
+**Fix OMOS `bunx` detection + CI build reliability.**
+
+- **Fix:** `entrypoint-user.sh` checked `command -v bunx` to gate the OMOS auto-install, but the OMOS image only ships the `bun` binary — upstream's bun installer never creates a `bunx` symlink and neither did our Dockerfile. The check always failed on a fresh OMOS image, so `bun x oh-my-opencode-slim@latest install` never ran and first-start OMOS setup would have printed `ENABLE_OMOS=true but bun is not installed.` even though bun was right there. Latent until now because the only exercised path had a persisted `oh-my-opencode-slim.json` from a prior install.
+  - Changed the gate to `command -v bun`.
+  - Changed both install invocations from `bunx oh-my-opencode-slim@latest install ...` to `bun x oh-my-opencode-slim@latest install ...`.
+  - Added `ln -sf bun /usr/local/bin/bunx` to the Dockerfile's OMOS block so interactive users can still type `bunx` by habit, and verified the symlink at build time (`test -L /usr/local/bin/bunx`).
+  - Smoke test now asserts the `bunx` symlink is present on the OMOS variant.
+- **Fix:** CI build robustness against transient GitHub/Gitea CDN failures. The first attempt at building v1.14.29b tripped on a single HTTP 502 from GitHub's release CDN mid-download (`zoxide-0.9.9-x86_64-unknown-linux-musl.tar.gz`), failing the entire OMOS build with no retry. Fix applied to every tool-download curl in the Dockerfile:
+  - `curl --retry 5 --retry-delay 5 --retry-all-errors` on both the `-fsSL` GET requests and the `-sI` HEAD requests used for `/releases/latest` redirect resolution. 5 attempts with 5 s back-off eats most transient CDN hiccups without failing the build.
+  - Added `[ -n "$V" ]` assertion after each version-resolution step. If the HEAD redirect ever fails to produce a tag name, the build fails fast with an empty-version message rather than trying to download `.../v//...` and producing a confusing 404.
+  - Same hardening applied to the optional Go install block (go.dev JSON feed + tarball download) and the nodesource apt-repo setup script.
+- **Security:** Added `apt-get upgrade -y` to the core-packages RUN step. Picks up any security/CVE fixes published between `debian:trixie-slim` base-image rebuilds. Paired with the existing `update` and `install` in the same layer so image history isn't bloated. Today this produced `0 upgraded` (base image is current), but it future-proofs against the next CVE drop.

Do **not** use `["python3", "-m", "mempalace.mcp_server"]` — the system Python cannot import from the uv-managed venv and you'll get `ModuleNotFoundError` / `MCP error -32000: connection closed`.
