5acb930821 feat(desktop-messages): render compact Buzz permalink chips (#5638)
**Category:** improvement
**User Impact:** Buzz channel, message, repository, pull request, and
issue links now open reliably and display recognizable context in the
desktop app.
**Problem:** Buzz links could appear as raw or ambiguous URLs, and
navigation links received during startup or community transitions could
be dropped before the UI was ready. Repository and issue shares in
particular required hover context to understand at a glance.
**Solution:** Queue desktop channel/message navigation until the UI is
ready, then render bare Buzz permalinks as icon-prefixed chips with
concise entity context while preserving user-authored Markdown labels as
ordinary links.

## Reproduction steps
1. Run the desktop app and open a channel containing bare
`buzz://channel`, `buzz://message`, `buzz://repo`, `buzz://pr`, and
`buzz://issue` URLs.
2. Confirm each bare URL renders as one cohesive chip with a type icon,
a useful name or shortened identifier, and no duplicated channel `#`
character.
3. Add an authored Markdown link such as `[design
discussion](buzz://issue?...)` and confirm the supplied label remains an
ordinary link rather than becoming a chip.
4. Select channel and message links and confirm they navigate correctly
in warm and cold-start states.
