v4.8.3: lazy in subagents too

New

• The ponytail ruleset now injects into subagents via a SubagentStart hook (#254) — spawned subagents stay lazy, not just the main thread.

Docs

• Korean README — README.ko.md (#283)
• OpenCode npm install + npm badge across the English and Spanish READMEs; dropped the obsolete command-symlink note (#285)
