feat: Integrate Ralph Loop mechanism for automated app development

[Rishabh-Bajpai]

Integrates the "Ralph Loop" mechanism, adopting Geoffrey Huntley's pattern as implemented in ChristianKuri/ralph-and-opencode, to enable a fully automated application development workflow.

This change adds:

• scripts/ralph/ralph.sh: The main loop runner that repeatedly executes OpenCode using the instructions.
• scripts/ralph/prompt.md: The system prompt to guide each fresh OpenCode agent instance during the iterations.
• prd.json.example: A format definition for structured feature plans the agent uses for tasks.
• .opencode/skills/*: Global skills like prd and ralph to assist developers in defining and formatting tasks before running the loop, as well as dev-browser to allow UI testing.
• AGENTS.md: Updated with usage instructions.

@copilot please review this PR and it looks like the ralph loop is not implemented properly in this PR (UI,feature are not that good). Please understand the whole code base and then improve the implementation. Also since the repo already have tasks maybe the current ralph implementation doesn't make any sense. Please re implement this feature with current code in the development branch.

@copilot please review this PR and it looks like the ralph loop is not implemented properly in this PR (UI,feature are not that good). Please understand the whole code base and then...

The Ralph Loop has been properly reimplemented in commit 33ebe71 to integrate with the existing Tasks system instead of copying shell scripts.

What changed:

1. Removed the poor UI — the inline-styled checkbox on the create-project form is gone entirely (both desktop and mobile).

2. Integrated with the Tasks panel — the Tasks sidebar now shows a Ralph Loop PRD Tracker section for the active project. It:

   • Shows the prd.json user stories with pass/fail status badges and a n/n done counter
   • Has an Init PRD button that scaffolds a starter prd.json directly in the project root via the new PUT /api/projects/{id}/prd backend endpoint
   • Has a Create Ralph Task button that pre-fills the task editor as a goal-type scheduled task with the ralph loop instruction and goal definition already set — the user just reviews and saves

3. Goal-type task integration — the pre-filled Ralph task uses the existing scheduler's goal type: OpenCode runs every 15 minutes, implements one story, updates prd.json, and outputs GOAL_MET: yes/no. The scheduler loops until all stories have passes: true.

4. Backend endpoints — GET /api/projects/{id}/prd reads the project's prd.json, PUT /api/projects/{id}/prd creates/updates it.

5. AGENTS.md — fixed formatting and added a proper Ralph Loop usage guide section.
