refactor(config): Invert negative flag aria2-fallback-disabled to enabled

[z-Fng]

Description

Invert negative flag aria2-fallback-disabled to enabled. Rename aria2-fallback-disabled to aria2-fallback-enabled.

Note: The original flag was unreleased, so no deprecation or backward compatibility is required.

Motivation and Context

Scoop/README.md

Lines 85 to 86 in 880f0ae

	- aria2-enabled (default: true)
	- aria2-warning-enabled (default: true)

Align with existing configuration naming conventions by using a positive flag instead of negative phrasing, avoiding double negatives and maintaining consistency across config options.

Relates to #6538

Summary by CodeRabbit

• New Features

  • Added the aria2-fallback-enabled setting, enabled by default. When enabled or unset, downloads fall back to the default downloader after an Aria2c failure; setting it to false aborts the download instead.

• Documentation

  • Updated aria2 configuration guidance and default-value annotations.
  • Updated the example repository URL to use HTTPS and added an issue reference to the changelog.

Walkthrough

The PR documents aria2-fallback-enabled and updates Aria2 failure handling to read ARIA2-FALLBACK-ENABLED. It also adds issue #6744 to the changelog and changes the repository example URL to HTTPS.

Changes

Aria2 fallback configuration

Layer / File(s)	Summary
Fallback setting documentation README.md, libexec/scoop-config.ps1, CHANGELOG.md	The documentation names aria2-fallback-enabled, marks it as enabled by default, and describes automatic fallback. The changelog references issue #6744. The repository example URL uses HTTPS.
Aria2 failure handling lib/download.ps1	When ARIA2-FALLBACK-ENABLED is unset or $true, Aria2 failure handling warns and uses the default downloader. When it is $false, the download aborts.

Priority: ➖ Normal

Merge Risk: ⚪ Minimal · up to 12ea1

The renamed setting appears consistent with the documented fallback behavior; no identified issue prevents merging after normal checks.

Invert negative flag aria2-fallback-disabled to enabled. Rename aria2-fallback-disabled to aria2-fallback-enabled.

Hi @niheaven , sorry for the interruption. Whenever you have some time, I'd really appreciate it if you could take a look at this PR. I realized that the config option I added in my previous PR (#6538) was confusing and inconsistent with the earlier design. It would be best if this could be reviewed before the next release 0.6.0, while the previous option has not been released yet.

For my other PRs, feel free to review and merge them if you have time; otherwise, it is totally fine to hold off until 0.6.1.

Thanks for the review!
