feat(views): surface the issue assignee as an @-tag on the heading

On a team or "by person" view you couldn't tell who owned an issue at a glance: the assignee was captured but folded inside the :LINEAR-ASSIGNEE-NAME: drawer, with nothing in the heading.

I render the assignee as a leading @-tag (:@eric:bug:backend:), behind a pearl-show-assignee defcustom (default on). I picked a tag over a heading suffix because Org strips tags before it hashes the title for sync, so the tag can't corrupt title-sync the way a suffix would. The @ prefix keeps it in its own namespace, separate from label tags: labels are tracked in their drawer, not read back from the heading, so the tag never gets mistaken for a label. The label-edit path preserves any @-tag when it rewrites the heading's tags, and edit-assignee refreshes the @-tag so a reassign doesn't leave a stale name until the next fetch.

Verified live against a by-person view: assigned issues carry their @-tag, unassigned ones stay bare.

 - *Title and description* -- type in the heading and the body. =pearl-edit-description= pops a focused compose buffer if you'd rather not edit inline.
 - *Priority* -- the Org priority cookie (=C-c ,=, or =S-up= / =S-down=). =[#A]/[#B]/[#C]/[#D]= are Urgent/High/Medium/Low; no cookie is None.
 - *State* -- =pearl-edit-state=, completing over the team's workflow states.
-- *Assignee and labels* -- =pearl-edit-assignee= / =pearl-edit-labels=, completing over the team's members and labels. Labels also render as Org tags on the heading (=:bug:backend:=), so you can filter, sparse-tree, and build agendas on them. The =:LINEAR-LABELS:= drawer stays the source of truth; hand-edited heading tags are ignored and rewritten from Linear on the next change or fetch, so change labels with =pearl-edit-labels=.

It is display-only -- the =:LINEAR-ASSIGNEE-ID:= drawer is the source of truth, and the tag stays outside the title hash, so it never affects sync.
 - *Comments* -- edit your own in place, or =pearl-create-comment= for a new one.
 
 Picking a constrained field writes the value into the buffer and marks it changed; it doesn't push until you save. The display name or label text is there to read -- Pearl reconciles by the underlying id, and a refresh rewrites the display from the remote, so hand-editing the visible name has no effect.
