feat: pearl — manage Linear issues from org-mode

Pearl fetches Linear issues into an org file and syncs edits back. It covers list / custom views / saved queries, per-issue and bulk rendering with comments inline, conflict-aware sync of descriptions, titles, and comments, field commands for priority / state / assignee / labels, and a transient dispatch menu. The render folds to a scannable outline and nests issues under a sortable parent.

Based on and inspired by Gael Blanchemain's linear-emacs.
