docs: add --dir flag documentation for qoder project-level skill installation

- Update README.md with --dir example for qoder
- Update docs/ADDING_A_HOST.md with project-level installation guide
- setup script already supports --dir with tilde expansion and CUSTOM_DIR override

This documents the project-level skill installation feature
that allows installing gstack skills to a custom directory.

+### 7. (Optional) Support project-level installation with `--dir`
+
+If your host supports installing skills to a project-local directory (e.g. for
+team-wide or repo-specific skill installations), extend the setup script to
+support the `--dir` flag. Add your host to the `case` statement that handles
+`CUSTOM_DIR` overrides in the `setup` script:
+
+```bash
+case "$HOST" in
+  myhost)
+    MYHOST_SKILLS="$CUSTOM_DIR"
+    MYHOST_GSTACK="$MYHOST_SKILLS/gstack"
+    ;;
+esac
+```
+
+Users can then install skills to a custom directory:
+
+```bash
+./setup --host myhost --dir ./my-project/.myhost/skills
+```
