Recording: capture page scroll as a "scroll" step with replay support ...

- content script debounces window scroll (250ms per pause, like inputs)
  into a "scroll" step; inner-container scrolls are ignored (they bubble
  from the page, so only document/documentElement targets count)
- replay sends replay_scroll to the content script, scaling recorded
  offsets to the current viewport
- "scroll" step type in shared API + server validation; timeline icon,
  AI-prompt coords line and stepTypes i18n (en/ru/uk)
- e2e: tall test page + scroll assertion; wait for composer focus
  instead of fixed delays (full-page stitch can take a while); mkdir
  /tmp/ltt-shots for video download; debug log on failure

Report page: swap header buttons, fix back navigation on share links ...

- the copy-link button now comes before "Start replay" in the header
- "Back to project" no longer depends on in-app history: on a cold
  share-link visit (note or recording opened by URL) it falls back to
  the report's project page — the detail GET now returns
  project_share_token; without a project reference it goes to the
  projects list

Record screen video around the cursor + console dump per recording ...

The recorder now captures continuous screen video instead of single frames
per event. captureVisibleTab is quota-limited to ~2 shots/sec, so the video
rides a CDP screencast (Page.startScreencast) over the chrome.debugger
connection: frames arrive throttled to ~15 fps, decimated past 600 to bound
memory. At submit, the GIF is cropped to a 512×512 square centered on the
cursor position from the mouse track at each frame's time, paced by real
frame gaps — a "video" of exactly the area the tester was looking at.
Firefox and a busy debugger degrade to the old per-event screenshots; the
video path is a videoCapture setting (default on, like hoverReplay).

Console errors now ride along with recordings: a MAIN-world document_start
tap wraps console.error/warn and the uncaught error/rejection handlers,
posts through the relay content script, and lands as "console" timeline
steps (capped at 200, text truncated at 2000 chars). New consoleCapture
setting; the server schema, shared types and the panel timeline (warning
icon) accept the new step type; replay counts such no-effect steps as
played so the played/total summary stays honest.

E2E generates a console error + warning mid-recording, asserts the console
steps, and validates the GIF header: 512px wide with 3+ frames.

Record the mouse path and play it back with a virtual cursor ...

- Recording: content script samples mousemove at ~25 Hz (2 px / 40 ms
  thresholds), batches it to the background every second and before
  submit; stored as reports.mouse_track (viewport + points, capped and
  decimated server-side) via a new alembic migration
- Replay: a virtual cursor (overlay arrow) walks the recorded path,
  scaled to the current viewport, dispatching synthetic mousemoves so
  JS hover handlers stay live; clicks snap the cursor to the target
- Replay errors: page-load timeout aborts with a clear message, a
  closed tab aborts, per-step failures (missing elements) are
  collected, reported in the flash and in the replay result
- Panel: "Start replay" button on recording reports talks to the
  extension through a new tiny relay content script (window messages,
  no extension-id config), with presence check and toasts for
  missing extension / no response / partial replay (en + ru)
