chore(ci): optimize gemini workflows and remove automatic triage

[utkarsh232005]

This PR removes scheduled runs and automatic triage triggers from Gemini workflows to save GitHub Action runtime minutes. Triage can still be triggered manually or via comment commands.

Summary by CodeRabbit

• Chores
  • Modified AI workflow triggers: Issue triage now requires an explicit comment command instead of triggering automatically on issue creation. Scheduled triage workflow changed to manual-only trigger, removing automated hourly execution.

📝 Walkthrough

Walkthrough

The PR modifies two GitHub Actions workflows to update trigger configurations and command routing. gemini-dispatch now listens for issue_comment created events instead of issues opened/reopened, and removes hard-coded triage command mapping in favor of command text parsing. gemini-scheduled-triage eliminates automated cron and file-watch triggers, leaving only manual dispatch.

Changes

Workflow Automation and Command Routing

Layer / File(s)	Summary
Gemini Dispatch event listener and command routing .github/workflows/gemini-dispatch.yml	The workflow event trigger switches from issues opened/reopened to issue_comment created. The command-extraction logic removes special-case triage routing for issue events, instead parsing @gemini-cli directives from incoming comment text.
Gemini Scheduled Triage trigger mode .github/workflows/gemini-scheduled-triage.yml	All automated triggers (hourly schedule, pull_request, and push filters) are removed; the workflow now executes only when manually triggered via workflow_dispatch.

Poem

🤖 Commands once flowed from issue states,
Now comments carry gemini's weight.
Scheduled runs bow to manual hand,
Dispatch and logic shake and brand—
A quieter, cleaner, command-first plan. ✨
