feat: append permalink to syndicated AP content + bump to 1.0.5

Notes and articles syndicated to ActivityPub now include a clickable
link back to the canonical post URL at the end of the content body.
This ensures fediverse clients display a visible permalink, since the
Note url property alone is not shown inline by most implementations.
