0.6.0: a spinner widget - #88

Conversation
`ui.spinner({ label, text })` draws a spinning glyph, a label and a
right-hand readout on one row. It keeps no timer of its own: the frame comes
from the app clock (RenderArgs.elapsed) and, while the spinner is active, the
container asks the app for another frame after this one, so a caller shows a
busy line with no interval to manage. `active: false` settles it on a done
mark without a layout change. Named frame sets (dots, arc, line, ascii) or
your own; terminals without Unicode get ascii and a plain done mark.

What
ui.spinner({ label, text }): a spinning glyph, a label, and an optional right-hand readout on one row.RenderArgs.elapsed; while active, the container callsctx.invalidate()so the app draws another frame after this one. The animation costs one frame per tick only while a spinner is on screen and active.active: falsesettles it on a done mark (✓, or*without Unicode) with no layout change, so "loading" and "loaded" share a line.dots(default),arc,line,ascii, or your own array;intervalin ms;color,labelColor,background,align.spinnerFrame()is exported so a status line elsewhere can show the same glyph.asciiautomatically.First consumer:
gh-pulse showin cli-tools, which fetches a range from GitHub in the background and needed a busy line.Version
0.5.1 → 0.6.0 in every hand-written place the version test ties together (library, CLI constant, demo, site badge, cobol adapter, workspace specifiers) and
