Adds SyncAdapter, a *Client-backed implementation of core.SyncCapable (SyncSource + SyncWriter) for board sync: ListUpdatedSince/ListAll follow the #85 cursor convention page-by-page and map to core.IssueSnapshot with StateGroup carrying Linear's workflow-state type (backlog/unstarted/ started/completed/canceled); GetIssue, UpdateFields (title/description/ labels/priority via issueUpdate), TransitionState (existing UpdateIssueState), AddComment (idempotent via a pilot-op:{idemKey} HTML marker scanned before reposting), and CreateIssue (team resolved from the projectID team-key param) round out the contract. Also adds the "url" field to Issue/issueListItem and their GraphQL selections, needed to populate IssueSnapshot.URL.

…ated idem comment scan, on-or-after delta (post-merge review of #94) (#99) Post-merge review of #94 found four defects in sdk/integrations/linear/sync.go: TransitionState sent a state NAME straight through as a GraphQL stateId (round-trip broken); AddComment's idempotency scan only checked the first comments page, letting retries duplicate-post once a marker fell off page 1; ListUpdatedSince used gt+second-truncated timestamps, silently dropping issues updated exactly at the watermark; and UpdateFields silently ignored unknown keys and wrongly-typed values instead of rejecting the patch.
