fix(i18n): migrate Chinese variants to CLAUDE_SKILL_DIR + bump to v2.30.0

- planning-with-files-zh: CLAUDE_PLUGIN_ROOT -> CLAUDE_SKILL_DIR (was 2.24.0)
- planning-with-files-zht: CLAUDE_PLUGIN_ROOT -> CLAUDE_SKILL_DIR (was 2.28.0)
- Same 3-level fallback chain as main skill
- All body references updated (session-catchup, templates, table)
