The li() helper in static/icons.js logs console.warn and returns ''
when an icon name is not in LI_PATHS. Five icon names referenced by
static/*.js were never registered, so their host elements rendered as
empty 0-size buttons / containers despite display:flex.
Five missing icons added:
- 'volume-2' — TTS speaker on every assistant message
(ui.js:3376; regression from #499; surfaced after
#1411 fixed CSS specificity in v0.50.255)
- 'chevron-up' — queue pill chevron (ui.js:2178; the '▲' fallback
only fired when li was undefined, not when it
returned '')
- 'hash' — Insights 'Messages' stat card (panels.js:883)
- 'cpu' — Insights 'Tokens' stat card (panels.js:884)
- 'dollar-sign' — Insights 'Cost' stat card (panels.js:885)
The Insights icons are a fresh regression from #1405 (v0.50.255).
Adds tests/test_issue1413_li_path_coverage.py — three tests:
1. Walk every li('NAME', ...) call across static/*.js, assert NAME
is registered in LI_PATHS. Prevents the entire class of bug.
2. Pin the five icons added by this fix so removal gets a clear
error message.
3. Pin the warn+empty-string contract of li() so the diagnostic
story in the test docstring stays accurate.
