Canary: Post-Deploy monitoring

Watch a live application after deployment. Alert on errors and regressions. Compare against a pre-deploy baseline.

Two modes:

• --baseline: capture the current state BEFORE deploying
• (default): monitor AFTER deploying and compare against baseline

Instructions

Phase 1: Setup

Parse the user's arguments and detect the deployment context.

# Detect current branch and recent deploy commit
git branch --show-current
git log --oneline -5
