t1224.2: Implement localdev add/rm commands

[marcusquinn]

Implements localdev add/rm commands for the local development environment manager.

Changes

• Port registry (~/.local-dev-proxy/ports.json): auto-assign ports from 3100-3999 range with jq primary / python3 fallback
• Collision detection: rejects apps that conflict with LocalWP domains (/etc/hosts #Local Site), registered apps, or registered domains
• mkcert wildcard cert: generates *.name.local + name.local cert pair via generate_cert()
• Traefik route file: creates conf.d/{name}.yml with wildcard Host rule (Host(\name.local`) || Host(`*.name.local`)`)
• /etc/hosts fallback: adds entry when dnsmasq resolver not configured; skipped when /etc/resolver/local is active
• localdev rm: fully reverses add — removes route file, cert files, hosts entry, registry entry
• localdev list: shows registered apps + LocalWP sites for context
• ShellCheck zero violations, bash -n syntax OK

Testing

# Syntax check
bash -n .agents/scripts/localdev-helper.sh

# ShellCheck
shellcheck -x -S warning .agents/scripts/localdev-helper.sh

# Help output
bash .agents/scripts/localdev-helper.sh help

# Validation (no mkcert/sudo needed)
bash .agents/scripts/localdev-helper.sh add 'My App'  # rejects invalid name
bash .agents/scripts/localdev-helper.sh list           # shows empty registry

Ref #1875

Warning

Rate limit exceeded

@marcusquinn has exceeded the limit for the number of commits that can be reviewed per hour. Please wait 3 minutes and 43 seconds before requesting another review.

⌛ How to resolve this issue?

After the wait time has elapsed, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

We recommend that you space out your commits to avoid hitting the rate limit.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

Please see our FAQ for further information.
