Orbit Pi 0.2.0

Added

• The Git page's Issues and Pull requests forms now discover the repository's own
  templates (.github/ISSUE_TEMPLATE/ Markdown and YAML issue forms, plus
  .github/PULL_REQUEST_TEMPLATE.md and its variants). A lone template applies
  automatically; with several, a Template picker (including Blank) chooses one.
  The choice prefills the title prefix and body skeleton — a YAML issue form is flattened
  into Markdown — and its labels: ride along on Create.

• The Git page's Issues and Pull requests forms can now draft their title and
  Markdown body with a Generate button. Add optional notes (or leave them blank) and
  Orbit makes the same one-shot, tool-free pi -p call the commit-message generator uses,
  reading the branch, its commits, and its changed files; when pi is missing or has no
  credentials it falls back to a local heuristic built from those same facts. Nothing is
  created until you review the draft and press Create.

• Every icon-only button across the app now carries the same native tooltip the
  send / stop button has — a localized label, usually with its keyboard shortcut
  (e.g. Toggle Terminal (⌘J)). Covers the top bar, sidebar, transcript copy /
  diff controls, composer add button, window caption buttons, Explorer, Review
  pane, Git, Usage, terminal, settings, and the picker / dialog controls.

• The sidebar's Projects list now defaults to most recent activity, with a
  sort control on the header to order workspace groups by recently added, name
  (A–Z or Z–A), or session count, or fall back to the manual added order. The
  choice persists in ~/.orbit-pi/workspaces.json and each project now records
  when it was added.

• Each project in the sidebar can now wear its own mark: pick from a curated
  set of the bundled HugeIcons and tint it with one of eight semantic colors
  (which follow the active palette). Reach it from the workspace header's ⋯
  menu → Icon & color, with a Reset back to the folder default. The choice
  persists in ~/.orbit-pi/workspaces.json beside the project list.

Fixed

• Images in issue/PR bodies, comments, and transcripts now render. The markdown image
  element forced a definite height: 0, and gpui derives a missing width from a definite
  height before the image decodes (0 × ratio), so a loaded screenshot collapsed to a 0×0
  box with only its border visible. The height is left auto now: the image scales to the
  reading column and taffy keeps its aspect ratio.

• Screenshots in replies load again when GitHub stored them as signed
  private-user-images.githubusercontent.com/…?jwt=… URLs. That JWT expires within
  minutes, so the app got a 404 and showed the alt-text fallback; the renderer rewrites
  the URL to the durable github.com/user-attachments/assets/<uuid> form encoded in the
  filename, which serves the same image.

• GitHub issue/PR bodies and comments now render screenshots that GitHub stored as raw
  HTML <img src="…"> tags when the line is inside a blockquote or list item — a quoted
  bug report is a common case. Previously only a standalone top-level <img> line became
  an image, so these showed the tag as text; the whole tag/its URL rendered as a link.

• The New pull request form's Base branch picker, and the Template pickers on
  both new-issue/new-PR forms, no longer float over the wrong part of the form or paint
  behind its fields. They are anchored to the chip that opens them (opening upward at the
  bottom of the PR form), draw above the form, and use the top branch selector's dropdown
  chip (glyph, value, chevron) and picker surface — list inset, rows, and search row for
  the branch list.

• The Issues tab's Label picker — the list filter chip and the detail view's
  Edit labels button — no longer opens at the page's top-right over the issue list.
  It anchors to the button that opened it, opens directly beneath it, and uses the same
  picker surface and rows as the branch selector.

• The conversation rail's active tick now follows every navigation path, not
  just wheel and scrollbar gestures. Clicking a tick and pressing ⌘↑/⌘↓ scroll
  the list programmatically, which never fired gpui's scroll handler, so the
  highlight stayed on the turn the reader left behind. Repeated ⌘↑/⌘↓ presses
  also walked a single turn and stalled; they now step through the transcript,
  and ⌘↑ from the live edge jumps back to the previous turn instead of doing
  nothing. The viewport hint wins while a run streams too, so scrolling up to
  read history moves the rail even mid-stream.

• The sidebar's project headers now stay pinned as you scroll through any
  expanded group, not just the active workspace. Previously only the open
  workspace's header was sticky, so a long list under the first project pinned
  while every other expanded project scrolled its header away.

• The "open in" menu's app icons are crisp and no longer tiny. macOS returns an
  icon whose largest representation is 1024×1024, and the menu embedded that PNG
  unchanged, so the renderer's single bilinear pass had to squeeze it into a
  14px slot — the blur. Icons are now rasterized to exactly the pixel size the
  menu draws (36×36 for the now-18px slot, matching a Retina blit 1:1), which
  also drops each embedded icon from roughly 1 MB to 2 KB.
