Rename the service to BugTrail ...

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.

Web: drop avatars, show navigation on shared project/report pages ...

- remove GnAvatar from the shell footer and the settings profile card
- AppShell falls back to a plain centered body when nobody is logged in, so
  ProjectPage and ReportPage can wrap it too: logged-in users get the nav
  shell on share-token pages, anonymous visitors keep the bare layout
- pages no longer carry their own max-width/padding (the shell body owns it)

Report page: full-width status select, icon-only edit button ...

- CompactSelect accepts "100%" width; the status select now fills its card
- kit cards wrap content in .card-content (padding:15px) on top of the card's
  own padding — move report-card padding there so controls reach the edges
- description edit is a GnIconButton (pencil, sm) instead of a labeled button

UI: redesign extension options page, panel tweaks from review ...

- options page: was losing its styles — the content pass overwrote
  assets/style.css (cssCodeSplit:false, shared asset name); options now
  emits assets/options.css and the page uses kit components (GnCard/
  GnInput/GnButton/GnSelect/GnAvatar) for the same look as the panel
- panel: hide the kit topbar "current section" chip entirely (page
  headers already carry context)
- ProjectsPage: vertical rhythm via a 20px column gap; project cards
  redesigned (name + compact copy icon, clamped description, footer
  link "Open →" instead of the clunky boxed button); gap between the
  create-modal action buttons
- e2e: options-page assert follows the new profile markup

UI polish: fix black-on-dark leftovers, spacing, unstyled elements ...

- 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

Web panel: Vue 3 + gnexus-ui-kit, auth, projects, reports, i18n ...

- 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
