PullMark 0.26.0

• GitHub Markdown links open in PullMark — click a
  github.com/…/blob/… (or raw) link to a Markdown file and PullMark
  fetches and renders it in-app instead of bouncing to the browser.
  The first click asks which behavior you want; your choice becomes
  the default (Settings → General), and ⌘-click always does the other.
  The link-status pill in the corner says where a hovered link will
  open — and flips live while ⌘ is held.
  • Provenance is always visible: a bar above the content reads
    owner/repo @ ref · path, shows the exact commit the ref resolved
    to, and carries the Open on GitHub control — you never have to
    wonder whether you're reading a local file or a repo.
  • Remote docs are browsable: relative links (./sibling.md,
    ../other/doc.md) resolve against the repo at the same pinned
    commit, images load the same way, and Browse Repo Files fetches
    the repo's whole Markdown tree into the sidebar. ⌘K accepts blob
    URLs and github.com/owner/repo too.
  • PRs keep precedence: a link into a repo you have open as a
    pull request opens in the PR space — the rendered diff when the
    file is part of the PR, the PR's browsed docs at its head branch —
    and a link to any other branch opens pinned to that branch.
  • Blame and branch compare work there too: the blame gutter and
    a Compare menu (rendered diff against any other branch) come along
    from the PR machinery.
  • Private repos work with the same GitHub credentials PRs
    already use; failures say loudly whether a file is missing or
    possibly unauthorized. Nothing fetched touches disk, sessions
    restore as references only, and no link is fetched without an
    explicit click.
  • Heading anchors now match GitHub's slug rules exactly
    (underscores survive, consecutive spaces keep their hyphens), so
    #section links written for GitHub land correctly in PullMark
    and vice versa.
• A calmer sidebar — four sections instead of six. Local folders
  and GitHub repos now share one Locations section (browsable
  roots, wherever they live — repo rows wear GitHub's book icon and
  show their ref), and Review Requests became a subgroup inside
  Pull Requests, unread badge intact.
• Every Location says what it is — a plain folder is just a
  folder; a git checkout gains a branch chip; a checkout of a GitHub
  repo adds a small book mark; a remote repo is the book itself. The
  chip is a control: on remote repos it switches the session's branch
  in place or opens another branch as a sibling Location (⌥-pick does
  it from the same list); on local checkouts it lists the repo's
  worktrees — each opens as its own Location — and, for
  GitHub-backed folders, other branches viewable from GitHub
  (preferring a worktree when one has that branch checked out).
  PullMark never checks anything out — disk state is discovered and
  read, never mutated. Fork + upstream remotes both count as the
  repo's identity, and links to a repo you have cloned on the linked
  branch now open the local file instead of fetching.
• Places show their README — selecting a folder, a folder in its
  tree, or a remote repo renders that directory's README (or index
  file) instead of an empty placeholder, GitHub-style.
• The ask dialog for GitHub links grew a Remember my selection
  checkbox: checked (the default), your choice becomes the standing
  policy; unchecked, it applies once — and the unchecked state is
  itself remembered.
