feat(skills): add client logos, theme-aware rendering, auto-update sk…

[ankurDelta4]

What does this PR do?

Adds a ClientLogo component that renders SVG logos for all supported MCP clients with theme-aware coloring (white on dark themes, black on light theme). Logos are integrated across Skills, Marketplace, Clients, and Config UI.

Also fixes several bugs introduced after upstream merges and a race condition in the auto-update feature.

Client Logos

• New ClientLogo component with Boxicons SVGs for: Claude Desktop, Claude Code, Cursor, Windsurf, Codex, Gemini, GitHub Copilot, Antigravity, MCPorter (OpenClaw), OpenCode, ChatGPT
• brightness-0 invert filter on dark themes (Tarsier, Midnight) → white logos
• brightness-0 on light theme (Daylight) → black logos
• MCPorter uses dedicated white/black SVG variants to preserve teal eye highlights
• Logos shown in: Skills filter tabs, SkillCard badge, CopySkillDialog, InstallSkillDialog, ConfigClientItem sidebar, ClientCard, Marketplace Skills tab

Fix: Bundle skill install failing for npx clients

npx skills add owner/repo treats the repo name as a single skill, not a bundle. For bundle sources (1 slash), all clients now route through file-copy so all skills in the collection are installed correctly.

Fix: Weekly auto-update skills feature

• Added skills_update_all Tauri command that runs npx skills update --agent <id> --yes in a non-blocking spawn_blocking thread
• Frontend SkillsAutoUpdater fires on app launch if >7 days since last run
• Fixed race condition: useRef guard prevents duplicate invocations when clients store updates multiple times during initial detection cycle
• Toggle in Settings → Updates section with last-updated display

Fix: Dashboard crash (auditEnabled not defined)

Wired auditEnabled to useSettingsStore().auditLogsEnabled after upstream merge introduced references to an undeclared variable.

Fix: TypeScript build error

Removed unused configuredClients variable (TS6133).
