chore: release v0.11.5

feat: SkillHub skill store (SDK-based, no CLI dependency)
- Rust SDK (skillhub.rs): HTTP search, index fetch, zip download+extract
- Node.js SDK (skillhub-sdk.js): mirrors Rust SDK for Web/Docker mode
- Skills page: new "Store" tab with full index browse + client-side filter
- Remove 6 old CLI-dependent commands, add 3 SDK commands
- Migrate assistant.js skill tools from ClawHub CLI to SkillHub SDK
- Fix index decode error ({total,skills} wrapper vs bare array)
- Fix skill name display (API field 'name' vs 'display_name')
- Clean up 13 dead CSS rules from old skills hero/tips UI
