commit-commands README describes /commit-push-pr behavior the command does not implement

plugins/commit-commands/README.md makes three claims about /commit-push-pr that the command cannot satisfy:

• line 78: "Analyzes all commits in the branch (not just the latest)"
• line 81: "Test plan checklist" as part of the PR description
• line 143: "Claude will analyze the full branch history for the PR description"

The command file (commands/commit-push-pr.md) injects only git status, git diff HEAD, and git branch --show-current; its allowed-tools contain no git log, and the prompt forbids using any other tools. Branch commit history is invisible to it, so the PR description is generated from the uncommitted diff alone.

The /commit section is fine: its "examines recent commit messages" claim is backed by git log --oneline -10 in commit.md. Happy to open a PR correcting the three claims.
