[Repo Assist] docs: improve setting descriptions in package.json

[github-actions]

🤖 This is an automated pull request from Repo Assist.

Summary

Three small but user-facing improvements to the package.json setting descriptions (shown in the VS Code Settings UI):

1. Fix typo in phpcbf.executablePath

Before:

Points to the phpcbf exectuable, eg: win: phpcbf.bat, other: phpcbf

After:

Path to the phpcbf executable. Examples: 'phpcbf' (if on PATH), '/usr/local/bin/phpcbf', '${workspaceFolder}/vendor/bin/phpcbf', '~/bin/phpcbf'. On Windows use 'phpcbf.bat'.

Also adds concrete path examples covering the most common configurations.

2. Update phpcbf.standard description

Before:

null, PSR1, PSR2, Symfony, WordPress etc. You can also point to a phpcs.xml rules file, eg: /file/path/phpcs.xml

After:

Coding standard to pass to phpcbf via --standard. Examples: PSR2, PSR12, WordPress, Symfony, or a path to a phpcs.xml file. Supports ${workspaceFolder}/phpcs.xml, ${workspaceRoot}/phpcs.xml (deprecated), ~/standards/MyStandard, and relative paths like ./phpcs.xml.

Changes:

• Adds PSR12 (which phpcbf supports natively)
• Mentions \$\{workspaceFolder} / \$\{workspaceRoot} / ~ / relative path support (these are already implemented in code but undocumented in settings)
• Framed as "what to pass" rather than listing standards vaguely

3. Expand phpcbf.configSearch description

Before:

Search for phpcs configuration files in the workspace.

After:

When true, automatically searches for a phpcs configuration file (.phpcs.xml, phpcs.xml, phpcs.xml.dist, ruleset.xml, etc.) in the file's directory and up to the workspace root, and uses it as the coding standard. Takes precedence over phpcbf.standard when a config file is found.

Changes:

• Lists the actual file names that are searched (matching the code's confFileNames array)
• Explains walk-up behaviour and scope
• Clarifies precedence over phpcbf.standard

Motivation

These descriptions appear directly in the VS Code Settings UI. Many user issues (#17, #38, #7) stem from not knowing about configSearch or the variable substitution support in standard. Better in-editor documentation helps users self-serve.

Test Status

✔ findFiles  7 tests pass
tests 7  pass 7  fail 0

(The change is documentation-only in package.json; no logic was changed.)
