[Unreleased]

Added

• Terminal copy/paste: Ctrl+Shift+C copies selection, Ctrl+Shift+V pastes from clipboard to PTY (TerminalPane.svelte)
• Terminal theme hot-swap: onThemeChange() callback registry in theme.svelte.ts, open terminals update immediately when flavor changes
• Agent tree node click: clicking a tree node scrolls to the corresponding message in the agent pane (scrollIntoView smooth)
• Agent tree subtree cost: cumulative cost displayed in yellow below each tree node label (subtreeCost utility)
• Agent session resume: follow-up prompt input after session completes or errors, passes resume_session_id to SDK
• Pane drag-resize handles: splitter overlays in TilingGrid with mouse drag, supports 2-col/3-col/2-row layouts with 10-90% ratio clamping
• Auto-update CI workflow: release.yml generates latest.json with version, platform URL, and signature from .sig file; uploads as release artifact
• Deno sidecar proof-of-concept: agent-runner-deno.ts with same NDJSON protocol, compiles to single binary via deno compile
• Vitest test suite: sdk-messages.test.ts (SDK message adapter) and agent-tree.test.ts (tree builder/cost), vite.config.ts test config, npm run test script
• Cargo test suite: session.rs tests (SessionDb CRUD for sessions, SSH sessions, settings, layout) and ctx.rs tests (CtxDb error handling with missing database)
• tempfile dev dependency for Rust test isolation

Changed

• Agent tree NODE_H increased from 32 to 40 to accommodate subtree cost display
• release.yml build step now passes TAURI_SIGNING_PRIVATE_KEY and PASSWORD env vars from secrets
