When context usage reaches 50% (yellow), a subtle hint button appears
in the context ring tooltip suggesting /compress. At 75%+ (red), the
hint intensifies with a warning style.
Clicking the button pre-fills /compress into the composer and focuses
it, so the user can add a focus topic or just hit send. No auto-fire
— the user stays in control.
- static/ui.js: conditional visibility + click handler in _syncCtxIndicator
- static/index.html: ctxCompressBtn element inside ctxTooltip
- static/style.css: muted button style, red variant for ctx-high
- static/i18n.js: ctx_compress_hint / ctx_compress_action in all 7 locales
Closes#524
