commit-dis — commit this session's work, here, now

Stage and commit the changes produced during this conversation onto the current branch. Nothing more. This is the quick "save what we just did" button.

THE RULES

1. Stay on the current branch. Do NOT create, switch, or rename a branch. Commit wherever HEAD already points — even if that's main. Never run git checkout -b, git switch -c, or git branch.
2. Only commit what this session changed. Stage the specific files you created or edited in this thread by path. Do NOT git add -A / git add . blindly — that risks sweeping in unrelated working-tree changes, untracked scratch files, or another task's edits. No overcommitting.
3. No push, no PR. Stop after the commit unless the user explicitly asks to push or open a PR.
4. One commit for the session's work unless the user asks otherwise.
