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.

+
+;; Tests for explicit title sync-back, a separate path from the description
+;; sync that shares the `pearl--sync-decision' gate.  Covers the title
+;; extractor, the title fetch and update helpers (stubbed at the HTTP
+;; boundary), the command's no-op / push / conflict branches, and the
+;; deliberate bracket-stripping lossiness: a bracketed remote title renders
+;; with its stored hash matching the stripped heading, so a no-op sync makes
+;; no API call and never clobbers the brackets on Linear.
