Desktop: prove 0.1.1 update and rollback lifecycle

[Bboy9090]

Purpose

Close the remaining PhoenixCore Desktop packaged-artifact lifecycle gap without weakening the downstream ARCWYRE artifact contract.

Stack

Base: convergence/phoenixcore-desktop-package (proven 0.1.0 package head 58160dae1b311ece2efc0e42f1e4f8b5eed98131)
Head: convergence/phoenixcore-desktop-update-rollback-proof

Candidate

Version-only package progression to 0.1.1 across npm, Tauri and Cargo. No dashboard feature changes are introduced by this lifecycle candidate.

Exact-head evidence

Candidate source: a8c9cf8cc2b19d3e63d253015d0276bf0d3d0903
Workflow: PhoenixCore Desktop Update Rollback
Run ID: 33441805141
Result: SUCCESS

Successful jobs:

• build-version-pair
• update-rollback (msi)
• update-rollback (nsis)

The Windows proof independently validated both installer kinds:

• clean runner
• install immutable 0.1.0 baseline
• source-bound installed smoke = 0.1.0 / 58160dae1b311ece2efc0e42f1e4f8b5eed98131
• update/install exact-head 0.1.1
• source-bound installed smoke = 0.1.1 / a8c9cf8cc2b19d3e63d253015d0276bf0d3d0903
• remove candidate
• reinstall known-good 0.1.0
• source-bound installed smoke = baseline source/version again
• final uninstall and clean removal

Truth boundary

Host package install/launch/update/rollback/uninstall lifecycle is now validated for both MSI and NSIS.

Still separate and not claimed:

• packaged Vite /api bridge behavior
• signing
• ARCWYRE-native runtime compatibility
• physical hardware validation
• release-candidate status

Downstream Wave 7 now has a pinned exact-byte importer for this retained artifact. Keep this PR draft until downstream artifact reconciliation is complete.
