Lataa TermCanvas 0.30.1

- Welcome demo rewritten for the v0.30 layout: shows project management + "+" in the left panel, code navigation + Monaco editor drawer on the right, session replay as a left-anchored drawer, Usage dashboard as a canvas-gap panel. Both side panels now demo their collapsed → expanded transitions on click, matching how the app actually boots
- Welcome demo Usage mock is now a dense five-row dashboard (4-card stat strip → hourly + 30-day charts → cache / projects / models bar lists → quota meters → heatmap ribbon) so it looks like the real UsageOverlay at small scale instead of a sparse placeholder
- Typography hierarchy across agent surfaces (agent chat, ChatPanel, MessageBubble, AgentStatusBar, ThinkingBlock, Hub, Diff, StatusBadges): semantic type tokens (tc-display / title / body / ui / label / eyebrow / caption, tc-mono / num) replace ad-hoc px sizes and hardcoded zinc greys so the agent subsystem no longer drifts from the rest of the app under either theme
Fixed
- Demo: drawer animations start flush against the panel seam instead of leaving a thin grey vertical line (border-l + border-r stacking at width=0 rendered as 2-px chrome)
- Demo: cursor click positions measured from DOM refs rather than hardcoded pixels, so they land on the correct targets regardless of container width
