feat: add SeaweedFS CT script + update AI.md with apt/dependency rules

- Add ct/seaweedfs.sh, install/seaweedfs-install.sh, seaweedfs.json
- AI.md: add anti-pattern #22 (apt-get → apt)
- AI.md: add anti-pattern #23 (core packages as dependencies)
- AI.md: fix template to use apt instead of apt-get
- AI.md: add checklist items for apt and core dependencies

+$STD apt install -y \

+```
+
+**Packages that must NOT be listed as dependencies (already available):**
+- `curl` — installed by `_bootstrap()` in `install.func`
+- `sudo` — base LXC package (and scripts run as root anyway)
+- `wget` — base Debian LXC package
+- `gnupg` / `gpg` — base Debian package
+- `ca-certificates` — base Debian package
+- `apt-transport-https` — obsolete on Debian 12+
+- `jq` — auto-installed by `ensure_dependencies` in `tools.func` when needed
+- `mc` — not a dependency, personal preference tool
+
+**When to omit the dependency block entirely:** If the app only needs packages provided by `setup_*` helpers (e.g., Node.js, PostgreSQL, Go) or is a prebuilt binary with no native deps, skip the "Installing Dependencies" block completely.
