Update default model routing to Composer 2.5, keep Zuko on supported Gemini 3.1 Pro, and align docs/install UX to Cursor 3.4+

[Copilot]

This updates the repo’s model policy to track current Cursor model support: default agents now target cursor-composer-2-5, Zuko remains on the currently supported gemini-3.1-pro, and user-facing version references move to Cursor 3.4+. The goal is consistency across README policy, agent frontmatter, orchestrator routing, and installer messaging.

• Model policy and agent metadata

  • Updated default agent model aliases from composer-2-fast to cursor-composer-2-5 in:
    • agents/aang.md
    • agents/katara.md
    • agents/toph.md
    • agents/appa.md
    • agents/momo.md
  • Kept Zuko on supported Gemini by ensuring model: gemini-3.1-pro in:
    • agents/zuko.md

• Orchestrator routing contract

  • Updated rules/orchestrator.mdc model policy text and routing table to reflect:
    • default: cursor-composer-2-5
    • Zuko: gemini-3.1-pro

• README model/version alignment

  • Updated Model Policy section and per-agent summaries to current model IDs.
  • Updated example frontmatter snippets to current aliases.
  • Updated subagent/version references from Cursor 2.5+ to Cursor 3.4+.
  • Updated installation requirements line to explicitly require Cursor 3.4+.

• Installer UX label consistency

  • Updated mode label in installers:
    • install.sh
    • install.ps1
  • Label now reads Team Avatar (Cursor 3.4+).

# before
model: composer-2-fast

Updated in 1765a1f. I reverted all Zuko references from gemini-3.5-flash back to gemini-3.1-pro in /home/runner/work/oh-my-cursor/oh-my-cursor/agents/zuko.md, /home/runner/work/oh-my-cursor/oh-my-cursor/rules/orchestrator.mdc, and /home/runner/work/oh-my-cursor/oh-my-cursor/README.md so the repo only uses currently supported models.
