Bug + trail: the recorded trail of actions leading to the bug.
User-facing rename in the web panel shell, extension manifest/popup/
options, API title, i18n locales and README; Firefox id is now
bugtrail@gnexus.space. Internal @ltt/* package scopes unchanged.

- stretch the kit's GnTabs (.tabs-panels shrink-wraps as a flex item) so the
  details grid and panels span the whole shell
- attachments tab: image thumbnails with filename/size tiles instead of a
  bare file list
- ScreenshotViewer: fullscreen lightbox with wheel/toolbar zoom capped at the
  image's natural resolution, drag-to-pan, Esc/backdrop close (a drag that
  ends off the image no longer closes it)

- theme.css: design tokens mirroring kit's hardcoded Tokyo Night palette
  (--ltt-* + --color-* aliases used by @ltt/ui and the overlay)
- CompactSelect: kit GnSelect is a 54px/600px form control — compact
  variant for toolbar filters and the report status select
- ProjectPage: filters were blank (null modelValue matches no <option>)
  and huge; drop the floating GnTable caption chip
- AppShell: empty topbar chip is now a user identity + logout; remove
  unused props
- ReportPage/ProjectsPage/SettingsPage: kit .card is width:max-content/
  max-width:340px — cards fill their grid now; toolbar shows localized
  project count; PageHeader on settings
- ElementContext/EnvironmentInfo: row separators, dim labels, formatted
  CAPTURED date, selector rendered as a code chip
- ScreenshotViewer: optional labels prop (panel passes i18n strings)
- i18n: ru plural rules ("1 проект"), no hardcoded EN strings on
  auth pages; hide kit's "Forgot password?" stub link
- extension overlay: define --color-* vars on the shadow mount point
- Makefile: ext:watch/ext:test targets never parsed (colon in
  .PHONY/rules) — renamed to ext-watch/ext-test
- shot.mjs: screenshot harness for visual review of all pages

- Monorepo packages: @ltt/shared (types+client), @ltt/ui (AnnotationEditor,
  ScreenshotViewer, ElementContext, EnvironmentInfo), @ltt/web (panel)
- Kit assets served at /assets in dev and build (absolute font URL workaround)
- Pages: login/register, projects, public project+report pages (token=auth),
  settings with en/ru switcher
- Annotation editor: pen/arrow/rect/text, Tokyo Night palette, undo,
  fraction coordinates, vector shapes persisted via attachment PATCH
