🧪 Test: Source file change detection (src/**) (#19)

## Summary

This PR tests the important file changes detection by modifying a source
file (`src/**`).

## What changed

- Added optional `Name` parameter to `Get-Greeting` function
- Updated documentation with new example

## Expected behavior

Since this PR changes `src/functions/public/Get-Greeting.ps1` (which
matches `^src/` pattern), the `HasImportantChanges` should be `true` and
build/test stages **should run**.

## Verification

Check the workflow run logs for:
1. "Check for Important File Changes" log group
2. Changed file `src/functions/public/Get-Greeting.ps1` detected
3. `HasImportantChanges: True` in the output
4. Build and test jobs should run
