mk-usage

1// mk-usage: the plan's limits (the 5-hour session and the week), where each
2// ends at the reset at the current pace, and when the subscription renews;
3// and the repository the session works in: branch, changes, sync with the
4// remote, the CI of its pull request, the version and the changelog.
5//
6// The quota, by default, at the end of the hint line under the prompt, a row
7// that is there anyway: named blocks, `Sesión 5h │ Semana │ Renueva`, in
8// Claude's gray (the engine paints that line itself). Git, by default, on one
9// row of the band above the prompt, colored by state, with a `c: commit`
10// button that opens the commit dialog. `/mk-usage` opens the detail of both,
11// `/mk-usage [git] franja|pie|oculto` moves either. Every word, threshold and
12// default is the person's (the manifest's `userConfig`). It reads what the
13// engine, git and gh already have: no model call, save the dialog's "write
14// with Claude" button, which spends tokens only when pressed.
