Add @streamdown/math plugin to the chat markdown renderer.
Inline ($x^2$) and block ($$...$$) math both supported with
singleDollarTextMath enabled. Plugin is gated to non-streaming state
to match the existing pattern for syntax highlighting — math renders
when the message completes, avoiding KaTeX re-render churn during
streaming. KaTeX CSS is imported in styles.css; ~30KB CSS + ~430KB
JS added to the bundle. Smoothness improvements during streaming
deferred to a follow-up.
- chat-messages: match tool rows by overlapping query/context/preview values
so preview-first `tool.progress` rows reliably adopt later stable-id
`tool.start` payloads instead of spawning ghost rows or mis-merging
parallel same-name calls; preserve prior args/result across phases.
- tui_gateway: emit full args + parsed result on `tool.start` / `tool.complete`,
drop redundant `tool.started` re-emit from `tool.progress`.
- electron/main: prefer SOURCE_REPO_ROOT before PATH `hermes` in dev so
local backend edits actually run; split hardening helpers into
`electron/hardening.cjs` with tests.
- thread/tool UI: one-shot enter animation keyed by stable ids, braille
spinner for running rows, Cursor-like disclosure rows, drill-down +
duration/count formatting via new tool-fallback-model.
- composer: extract `text-utils`, drop liquid-glass overrides.
- right-rail: split preview-pane into preview-console / preview-file.
- runtime: incremental external-store runtime + runtime-readiness gate;
onboarding store + tests; route-resume hook test.
- regression tests for live tool reconciliation (parallel tools, id-less
progress, preview-first rows, structured args/results).
Solid foreground-on-background send/voice-conversation circle (black-on-white
in light, white-on-black in dark) anchors the right edge as the primary CTA
instead of the orange theme primary. Bumps the primary control to 2.125rem so
it visually outranks the ghost mic/plus controls. Opens up the surface padding
(0.625rem x / 0.5rem y) so the input row breathes around its controls, and
nudges the corner radius from 20 to 24px for a slightly pill-ier silhouette.
LiquidGlass distortion is preserved.
Introduce the Electron desktop app with a split app/chat/settings structure and shared nanostore state so UI areas own their state instead of routing it through the root.
