feat(web): group sidebar by project and refine session motion and chrome

• Group sidebar threads under collapsible project folders with quick new-thread actions
• Replace boxed frame lead badge with a quiet inline breadcrumb header
• Tune session prompt rise, work-log collapse, step expansion, and popover/menu transitions to sub-300ms ease-out curves
• Add press feedback and blur-masked copy state transitions across session and composer controls
• Scope transcript mask CSS custom properties with @Property (inherits: false) to avoid child style recalculations

Follow-up on this branch

Merged the latest canary (one conflict in queue.tsx, kept canary's parked notice), then:

• Sidebar grouping and ordering: group by project, status or priority; order by last updated or created, from a dense display menu shared with Threads. Empty projects stay listed and sort by their own last change; new threads start in the primary space; collapse state is kept and collapsed groups mount only the open thread.
• Thread statuses, Linear-like: enqueued and working follow the runs (a run starting sets working, which stays when it ends; parked prompts set enqueued); review, settled and cancelled are set only by the user. An app.db migration derives existing statuses again, keeping user-set ones.
• Threads page: renamed from All Threads; dense menus with a Color submenu, Remove instead of Session Color, Untitled Group for new groups.
• Sidebar toggle: instant from the button and the shortcut on every page; frames resize in the same frame as the workspace, so the session page no longer jerks.

Checked with vp check, vp run typecheck and the app server E2E suites (threads, sync, tracking, reads, schema), and in the Electron app.
