Prepare Ceiling 1.5.21

[tsouth89]

Summary

• prepare the unpublished notification-reset fixes and reliability hardening as 1.5.21
• replace the release smoke test's faulty custom PROPVARIANT marshaller with Windows Shell property inspection
• update release notes and all version sources after the immutable v1.5.20 tag failed before draft creation

Validation

• powershell.exe -ExecutionPolicy Bypass -NoProfile -File scripts/local-check.ps1 -All -Version 1.5.21
• compiled and silently installed a minimal Inno fixture; Windows Shell reported System.AppUserModel.ID = io.github.tsouth89.ceiling
• parsed scripts/windows-smoke-install.ps1 with the PowerShell parser

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your recent review volume is higher than typical usage, so adaptive limits are currently applied.

Next review available in: 59 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Pull request overview

Prepares the Ceiling project for the 1.5.21 release by bumping all version sources, updating release notes/changelog, and hardening the Windows release smoke test to read the Start Menu shortcut’s AppUserModelID via the Windows Shell (avoiding a brittle custom PROPVARIANT marshaller).

Changes:

• Bump versions to 1.5.21 across env/Cargo/Tauri/package metadata (and update build number).
• Replace the Windows smoke test’s custom Shell Link property-store + PROPVARIANT interop with Shell.Application + ExtendedProperty("System.AppUserModel.ID").
• Update changelog and GitHub release notes links/installer filenames for 1.5.21.
