fix(desktop): preserve Welcome banner dismissal - #5406

## Summary

- remove the complete Welcome guidance surface when dismissal reaches
`hidden`
- preserve dismissal across the private and starter Welcome channels for
the active identity
- assert the starter channel's actual `welcome-everyone` title on
re-entry

## Why

PR block#5330 introduced two deterministic Desktop E2E failures:

- the inner banner unmounted, but `welcome-composer-guidance-layer`
remained
- the re-entry test expected case-sensitive `Welcome` while navigating
to `welcome-everyone`

The state hook also scoped completion to channel IDs while `ChannelPane`
remounts during navigation. The Welcome guidance is one experience
spanning both Welcome channels, so completion now survives that remount
while remaining identity-scoped.

## Validation

At `b577eb42edffe889f63566f2457eacea720f3593`:

- `pnpm -C desktop typecheck`
- focused Biome check for all four changed files
- E2E build
- both `welcome-everywhere banner` integration tests repeated three
times: **6/6 passed**
- mandatory pre-push desktop check, typecheck, and full desktop unit
suite: **4,535 passed**
- `git diff --check`

Pull in #5406 (banner-dismiss fix) and successful_steer_deliveries
field added to TaskMeta. Resolves conflicts in lib.rs and pool.rs by
taking both permission_decision_tx (branch) and
successful_steer_deliveries (main) as distinct fields — each is
independently required.
