Add Warp AI agent support

[DevenDucommun]

Summary

This PR adds support for Warp as an AI agent in spec-kit.

Changes

• Added Warp to AGENT_CONFIG as IDE-based agent
• Updated CLI help text to include warp option
• Added Warp to README supported agents table and examples
• Updated release package and GitHub release scripts
• Added Warp support to bash and PowerShell agent context scripts

Configuration

• Agent Type: IDE-based (no CLI check required)
• Directory: .warp/commands/
• Format: Markdown
• Arguments: $ARGUMENTS

Testing

The code changes have been verified locally. Template package generation will work correctly in GitHub Actions' Linux environment (which has GNU coreutils).

After this PR is merged and a new release is created, users will be able to run:

specify init my-project --ai warp

Update: Fixed Integration Based on Testing

After testing with Warp, I discovered that Warp does not support reading custom slash commands from local files like .warp/commands/. Instead, Warp uses:

• WARP.md for project-specific rules and context
• Warp Drive (cloud-based) for custom prompts

Changes Made

✅ Created agent_templates/warp/WARP.md template with spec-kit workflow documentation
✅ Updated release script to copy WARP.md instead of generating .warp/commands/
✅ Tested integration - Warp successfully reads and uses the WARP.md file

How It Works

Users run specify init --ai warp which creates a WARP.md file. When users work in that project:

1. User asks: "What spec-kit commands are available?"
2. Warp reads WARP.md and lists all workflows
3. User asks: "How do I run specify?"
4. Warp guides them to run .specify/scripts/bash/setup-plan.sh specify

Testing Confirmed

User: what are the project setup instructions
Warp: [Reads WARP.md] TEST SUCCESSFUL

User: what spec-kit commands are available
Warp: Lists all spec-kit commands from WARP.md

User: how do I run the specify command
Warp: Run `.specify/scripts/bash/setup-plan.sh specify`

Comparison with Claude Integration

Claude: /speckit.specify → Direct slash command execution
Warp: Ask Warp → Guides to .specify/scripts/bash/setup-plan.sh specify

Future Enhancement

Submitted feature request to Warp for local project-based slash commands (similar to Claude's .claude/commands/). Until then, the WARP.md approach provides working integration.

The integration is now tested and functional! 🎉
