Fix config file lookup when project path contains spaces

[mgacy]

Short description 📝

Fixes an issue where the .prefire.yml config file is not found when the project path contains spaces. The plugin passes percent-encoded paths (e.g., My%20Project) which causes the file lookup to fail.

Solution 📦

Decode percent-encoded characters in ConfigPathBuilder.possibleConfigPaths() before constructing the URL:

let decodedPath = path.removingPercentEncoding ?? path
var configURL = URL(filePath: decodedPath)

The root cause is that the plugin uses String(describing: target.directory) which percent-encodes spaces. Alternative fixes were considered:

1. Change plugin to use target.directory.string — This fixes the encoding but reintroduces deprecation warnings that were removed in Removing swift 5.x support and fixing warnings #101.

2. Change plugin to use target.directoryURL.path(percentEncoded: false) — This is the ideal solution but directoryURL is only available in swift-tools-version 6.1+, and the package currently targets 6.0.

3. Decode in the executable (this PR) — A defensive fix that handles percent-encoded input regardless of source, requires no plugin changes, and introduces no warnings. This complements the fixes in Fixed issue where config paths containing spaces #141.

Implementation 👩‍💻👨‍💻

• Add removingPercentEncoding call in ConfigPathBuilder.possibleConfigPaths() before creating URL from input path

Closes #153

Hey! Thanks for the quick fix - this solves the spaces-in-path issue nicely, and the test is a great touch. 👍

Looks good to me. Let’s merge it as-is.
