Gitea's notifications feed names no per-row reason, so the adapter
collapses every row under one fixed NotificationReason::Other spelling
— and the claw's triage mapped every Other to Surface: the notification
reached the device queue and never a dispatch. A comment on a thread
the account authored could therefore never wake the agent on a
reason-less forge, whatever the watches said.
The adapter now publishes that spelling as gitea::COLLAPSED_REASON —
it is the seam's contract, not a detail — and the triage treats it as
the known shape it is: a notification on a thread of the account's own
dispatches the implementer. A spelling no adapter owns still surfaces;
an unknown shape remains the user's to judge, never the agent's to
guess at.
