* feat(desktop): render agent-to-agent messages as attributed cards, not user bubbles
Bot-to-bot deliveries arrive on the user role (alternation requires
it) but are not the human speaking — they rendered as if the user
typed them. Detect the delivery prefix ('Message from 🤖 <sender>: …',
emoji-less, and the legacy bracket form) and render an attributed
inter-agent card: left-aligned, robot + sender header, 'agent message'
label, body through the same minimal markdown pipeline. Anchored regex
cannot fire mid-prose. Same pattern as ProcessNotificationNote.
Presentational only; content/roles/caching untouched.
* reshape: inter-agent card -> Grok-style compact timeline notice
Per maintainer screenshot: the delivery renders as a subtle centered
'🤖 Message from <sender>' notice (ProcessNotificationNote's shape),
with the delivered text behind a 'show message' expander instead of a
full-width card. The recipient's reply remains a normal assistant
message below it.
* feat: sender avatar on the inter-agent notice
The delivery prefix may carry the sender's profile handle —
'Message from 🤖 <Display Name> (@<handle>): …'. The notice resolves
it through profiles.list (has_avatar) + profiles.get_asset and renders
the sender's actual avatar in place of the 🤖 glyph, with module-level
memoization (one resolution per sender per window) and inflight
de-dup. Glyph fallback covers handle-less prefixes, older gateways
without profiles.*, avatarless profiles, and failures. 'hermes'
resolves to the primary profile by convention. Tests 6/6.
* lint: sort the $gateway import (perfectionist/sort-imports)
