- fix RetroAchievements HTML/challenge responses so they are logged at Information instead of filing bug reports (bugs #68823-68828)

- clear read-only files during updater bootstrap and classify access-denied/file-in-use conditions as expected (bug #68830)

- bump all app, updater, tests and manifest versions to 5.8.4

- add 5.8.4 release notes and update the docs version references, dependency versions and test counts

- bump Meziantou.Analyzer to 3.0.315 and SharpCompress to 0.50.7

- add scripts/publish-fallback-r2.ps1: uploads the four release and four updater ZIPs, verifies public URLs and updates version.txt only after every bundle is available

- document the R2 fallback release step and the gitignored local credential block

- document the drive D test temp-path rule in AGENTS.md

- run scripts/publish-fallback-r2.ps1 after the GitHub release is created/updated, gated by create_release

- pass the R2 credentials from repository secrets and publish bundles before version.txt

- document that workflow releases are mirrored automatically while local packaging still runs the script manually

….316, CHDSharp 1.5.2, PBPSharp 1.1.5)

- Configure nullable-contract, DTO-accessor and style inspections that are false positives for this codebase as hints, so 'jb inspectcode -e=WARNING' reports zero warnings.

- Replace disposed ManualResetEventSlim captures in the audio regression test with TaskCompletionSource to clear AccessToDisposedClosure.

- Refresh NuGet package references (Avalonia, Meziantou.Analyzer, CHDSharp, PBPSharp, SharpCompress, Tomlyn, NLayer, System.Drawing.Common).

Bumps Meziantou.Analyzer from 3.0.320 to 3.0.322
Bumps Tomlyn from 2.10.2 to 2.11.1

Add a regression test for #69675, #69680, #69681, #69685, #69688 and #69689. These reports came from 3.12.0.0, which logged a 429 and a duplicate 'API request failed.' error for every OpenMSX launch during a rate-limit window. Current Stats logs exactly one Information event for the emulator call, so BugReportApiSink (Warning+) never files it.
