Clean branch structure

Severity: Recommended

Check automatically:

# List all remote branches
git branch -r | grep -v HEAD

Look for:

• origin/main or origin/master (production - required)
• origin/staging (pre-prod - expected)
• No origin/dev or origin/develop (anti-pattern)
• No stale long-lived branches (release, hotfix, old version branches)

Correct flow: feature-branch → staging → main (production)

Pass criteria:

• Only main/master + staging as long-lived branches
• No permanent dev/develop branch
• No other long-lived branches (release/, hotfix/, v1, v2, etc.)

Fail criteria:

• dev or develop branch exists
• Other long-lived branches that aren't main/staging

If suspicious branches found, ask user: "Found these long-lived branches: [list]. Are these actively needed? Recommended pattern is feature-branch → staging → main, with only main and staging as permanent branches."

Evidence to capture:

• List of all remote branches
• Any flagged long-lived branches and user justification
