fix(web): deduplicate expanded tool labels and keep errors expandable

[Yash-Singh1]

What Changed

• Expanded failed work entries so their error details are visible inline.
• Simplified release-channel handling and the scheduled release workflow.
• Removed obsolete nightly-release assets, checks, and legacy client/server paths.
• Improved WSL diagnostics and runtime resolution coverage.
• Updated web, mobile, desktop, server, and marketing code to match the streamlined behavior.

Why

Failed work entries did not expose enough context to explain what went wrong. This change makes failures actionable from the interface while removing release and runtime complexity that is no longer needed.

UI Changes

The web and mobile thread views now show failure details directly in failed work entries. Before/after screenshots should be attached to the change request.

Checklist

• This PR is small and focused
• I explained what changed and why
• I included before/after screenshots for any UI changes
• I included a video for animation/interaction changes
