docs: npm install + badge for OpenCode, drop obsolete symlink note

The plugin registers the /ponytail commands itself now (#197), so the manual
ln -sf workaround is obsolete. Add the npm install snippet + version badge,
and bring README.es.md's OpenCode section up to parity with the English one.

 The `./` path resolves against your project's `opencode.json`; to share one checkout across projects, point it at the absolute path of the `.mjs` instead (it finds its `hooks/` and `skills/` relative to its own file).
 
-The plugin path loads the ruleset everywhere, but the `/ponytail` commands are separate files in `.opencode/command/` that OpenCode only discovers from your project or the global commands dir. To use them outside this checkout, link them once: `ln -sf /absolute/path/to/ponytail/.opencode/command/* ~/.config/opencode/command/`.
