fix: use --tags (not --tag) for clawhub skill publish

ClawHub does not sync from GitHub. Each OpenClaw skill is pushed with the
clawhub CLI at its own version, so the published copies can drift from the
repo the same way the plugin manifests did (#260). This adds a one-pass
publisher that pushes every generated .openclaw/skills/ skill at the
package.json version, with --dry-run to preview, and documents it in the
README next to the build step.

+The OpenClaw skill package (`.openclaw/skills/`) is generated from `skills/`; rerun `node scripts/build-openclaw-skills.js` after changing a skill, the test suite fails if it is stale. To publish the skills to ClawHub, run `clawhub login` once, then `node scripts/publish-openclaw-skills.js` (it publishes all six at the `package.json` version; pass `--dry-run` to preview).

+// Publish the generated OpenClaw skills (.openclaw/skills/) to ClawHub.
+//
+// ClawHub does not sync from GitHub: each skill is pushed explicitly with the
+// clawhub CLI and carries its own version. This publishes every generated skill
+// in one pass, versioned from the repo's package.json so ClawHub tracks the repo
+// instead of drifting (the same drift that hit the plugin manifests in #260).
+//
+// Prereqs:
+//   - `clawhub login` once (registry auth persists)
+//   - skills must be current: run `node scripts/build-openclaw-skills.js` first
+//     if you changed a skill (CI fails if the committed copies are stale)
+//
+// Usage:
+//   node scripts/publish-openclaw-skills.js            # publish all as latest
+//   node scripts/publish-openclaw-skills.js --dry-run  # preview, upload nothing
+//   (any extra args are passed through to `clawhub skill publish`)
