fix: exclude PDB files from release artifacts and installer (closes #39)

[KrennicMS]

Summary

Closes #39.

PDB debug symbol files were being included in release artifacts. Three layers of defence added:

1. src/HomeAssistantWindowsVolumeSync.csproj

Added <DebugType>none</DebugType> and <DebugSymbols>false</DebugSymbols> to the Release PropertyGroup. PDBs are never generated at publish time.

2. installer/windows.iss

Added Excludes: "*.pdb" to the [Files] entry. Belt-and-suspenders for the installer.

3. .github/workflows/release.yml

Added a "Remove PDB files from publish output" step before zip creation. Recursively deletes any .pdb files from both publish directories as a final safety net.

Pull request overview

This PR addresses issue #39 by preventing .pdb debug symbol files from being included in end-user release artifacts (zip packages and the Inno Setup installer), adding multiple safeguards across the build, packaging, and installer layers.

Changes:

• Disable PDB generation for Release builds in the app .csproj.
• Exclude *.pdb from the Inno Setup installer file collection.
• Add a GitHub Actions workflow step to delete any remaining .pdb files from publish outputs before packaging.
