🩹 [Patch]: Name the helper module after the action (Debug.Helpers) (#32)

Aligns the helper module with the action helper-module naming standard:
name it after the action (`Debug.Helpers`) instead of the generic
`Helpers`.

This action loads the shared framework `Helpers` module (for `LogGroup`)
alongside its own helper module, so the generic name collided in the
runner's single module session. An action-scoped name removes the clash.

## Changes

- `src/Helpers.psm1` → `src/Debug.Helpers.psm1`
- Updated the entry-script import in `src/main.ps1`.

No runtime logic changed (100% file rename + one import path).

## Validation

`Debug.Helpers` imports and exports `Set-MaskedValue`; `main.ps1`
parses; PSScriptAnalyzer clean. Action-Test in CI is the full gate.

Part of PSModule/Process-PSModule#364. Standard: the "Name helper
modules after the action" rule in the GitHub Actions coding standard
(MSXOrg/docs#24).
