chore(claude): improve Claude Code integration

[nanotaboada]

Summary

• Add CLAUDE.md importing .github/copilot-instructions.md with a ## Claude Code section pointing to /precommit
• Add .claude/settings.json with ./mvnw * tool permissions
• Add .claude/commands/precommit.md with the full pre-commit checklist as a /precommit slash command
• Replace github.copilot-chat with anthropic.claude-code in .vscode/extensions.json
• Fix co-author in copilot-instructions.md to Claude Sonnet 4.6
• Add .claude/settings.local.json to .gitignore

Notes

.claude/settings.json and .claude/commands/ are committed intentionally — they contain no secrets and are useful for any contributor using Claude Code. .claude/settings.local.json remains gitignored for machine-specific overrides.
