feat(pull-requests): add full PR workspace with overview, files, and conversation views

Introduce a multi-pane PR workspace replacing the single review view.
New components: PullRequestWorkspace, OverviewPanel, FilesPane,
ConversationPane, FileTree, InlineComment, MergeButton, ReviewBar,
and ReviewSidebar. Add PR detail query, merge mutation, and review
submission to React Query hooks. Support checkout and worktree
creation from the PR view. Wire up URL-driven view navigation
(overview/files/conversation).
