refactor: rename CLAUDE.md to AGENTS.md (#8052)

## Summary

Pure rename of CLAUDE.md files to AGENTS.md (no content changes).

## Changes

| Old Path | New Path |
|----------|----------|
| `.github/CLAUDE.md` | `.github/AGENTS.md` |
| `.storybook/CLAUDE.md` | `.storybook/AGENTS.md` |
| `browser_tests/CLAUDE.md` | `browser_tests/AGENTS.md` |
| `src/CLAUDE.md` | `src/AGENTS.md` |
| `src/components/CLAUDE.md` | `src/components/AGENTS.md` |
| `src/lib/litegraph/CLAUDE.md` | `src/lib/litegraph/AGENTS.md` |

Root `CLAUDE.md` deleted (content will be merged into `AGENTS.md` in
follow-up PR).

## Follow-up

A second PR will add glob-based guidance files and consolidate
redundancies.

-## Repository Setup
-
-For first-time setup, use the Claude command:
-
-```sh
-/setup_repo
-```
-
-This bootstraps the monorepo with dependencies, builds, tests, and dev server verification.
-
-**Prerequisites:** Node.js >= 24, Git repository, available ports for dev server, storybook, etc.
-
-## Development Workflow
-
-1. **First-time setup**: Run `/setup_repo` Claude command
-2. Make code changes
-3. Run tests (see subdirectory CLAUDE.md files)
-4. Run typecheck, lint, format
-5. Check README updates
-6. Consider docs.comfy.org updates
-
-## Git Conventions
-
-- Use `prefix:` format: `feat:`, `fix:`, `test:`
-- Add "Fixes #n" to PR descriptions
-- Never mention Claude/AI in commits
