Lataa TermCanvas 0.33.0

- Stash button on terminal cards in the sidebar: hover any terminal to reveal a tray icon that stashes it, symmetric with the restore icon in the stash section.
- Stash section in the left sidebar with dedicated collapsible area, explicit restore/destroy buttons, and confirmation dialog for destructive actions.
- Cmd/Ctrl+Click on URLs in the terminal now opens them in the default browser.
- shadcn component system initialized (Radix + Nova) with alert-dialog, collapsible, button, and tooltip primitives.
Changed
- Project tree always shows the branch row (removed flat-mode special case). Single-worktree projects display the branch name as a second level, matching multi-worktree layout.
- Renamed isMain to isPrimary across the worktree data model to clarify it means "primary git worktree" (directory identity), not "main branch".
- Terminal title resolution rewritten: customTitle stands alone (no longer concatenated with process title), extractIntent() extracts meaningful titles from prompts by stripping code blocks, file paths, and polite prefixes.
- Project-level [+] button now creates a worktree (terminal creation moved to each branch row's own [+]).
- Canvas edge resize handles restyle as Figma-style midpoint rectangles.
Fixed
- ConfirmDialog redesigned: added close button, smooth hover transitions, and danger button now uses project color tokens (var(--red)) instead of raw Tailwind red.
- Branch row was hidden for single-worktree repos on feature branches because isMain (git worktree identity) was conflated with "is main branch".
