PLT-0000 feat(cli): add dedicated redeploy command

[uptickmetachu]

Motivation

The bump command's --redeploy flag conflates image bumping with redeployment. A dedicated redeploy command provides a clearer, simpler interface when you just want to trigger a redeployment without any image changes.

Changes

• Added redeploy task to core.py that updates the bump UUID field to trigger redeployment
• Supports the same filtering (filter, exclude, autoexclude_inactive), interactivity, push, and skip_migrations options as bump
• Skips all image resolution logic since no image change is needed

Test plan

• Run gitops redeploy -f <app> and verify it updates the bump UUID in deployment.yml
• Run gitops redeploy -f <app> --push and verify commit + push behavior
• Run gitops redeploy -f <app> --skip-migrations and verify commit message flag
