feat(commit-commands): add commit-push command

[getsolaris]

Summary

• Add /commit-push command to fill the workflow gap between /commit and /commit-push-pr

Motivation

Currently, the commit-commands plugin has:

• /commit - stages and commits only
• /commit-push-pr - creates branch + commits + pushes + creates PR

However, there are many cases where you want to commit + push without creating a PR:

• Working on a collaborative branch (push without PR)
• Accumulating multiple commits before creating a PR later
• Just wanting to trigger CI/CD

Changes

Command	Behavior
/commit	add + commit
/commit-push	add + commit + push (NEW)
/commit-push-pr	branch + commit + push + PR

Files Changed

• commands/commit-push.md - New command definition
• README.md - Documentation for the new command

Test Plan

• Run /commit-push command in Claude Code
• Verify changes are committed and pushed
• Verify no PR is created
• Verify it stays on current branch (no new branch created)
