Wes f7a3988ba1 fix(desktop): preserve shared agent fidelity (#3553)
## Summary

Fixes two distinct fidelity failures in direct agent sharing:

- The sender now puts the same effective avatar shown on the agent card
into People-share and file-export snapshot PNGs, including
profile/kind:0 fallback avatars.
- The importer now persists the visible PNG body as the portable avatar
instead of ignoring it in favor of sender-local manifest references.
- Export materializes inherited runtime, provider, and model identifiers
verbatim, while preserving explicit definition values. It does not
translate or substitute configuration for a different recipient setup.
- Sharing waits for a profile-only fallback avatar query, preventing an
early-click race.

The PNG import path keeps the existing safety invariant: decode is
capped at 2048×2048 / 32 MiB and re-encoded avatars above the 2 MiB
inline limit fall back to the manifest reference. The exact transparent
1×1 no-avatar placeholder is ignored.

The original Tyler↔Wes screenshot demonstrates both stages: Wren's
attachment had an avatar that disappeared after **Add agent**
(receiver/import failure), while Pinky's attachment was already blank
(sender/projection failure).

### Related issue

N/A — reported and traced in the linked Buzz conversation.

### Testing

- `cargo test --manifest-path desktop/src-tauri/Cargo.toml
commands::personas::snapshot` — 57 passed
- `pnpm exec tsc --noEmit`
- Biome check on changed frontend/E2E files
- Pre-push hooks:
  - desktop check
  - desktop tests
  - desktop Tauri tests — 1853 passed, 14 ignored
  - file-size ratchet

The People-share E2E regression asserts that a profile-only avatar
reaches `avatarPngDataUrl` in the real encode command payload.
