Fix extensionless files missing from [Content_Types].xml manifest

[Copilot]

The genContentTypesXml() method only processed files from VsixManifestBuilder's own collection (this.files), excluding files added by other manifest builders like VsoManifestBuilder. This caused extensionless executables and other files to be missing from the Content_Types.xml Override section, breaking digital signing tools.

Changes

• Modified genContentTypesXml() to accept and process the merged packageFiles parameter containing all files from all builders
• Updated finalize() to pass the merged file collection to genContentTypesXml()
• Added test fixture with extensionless Linux executable and validation test

Before:

private genContentTypesXml(builders: ManifestBuilder[]): Promise<string> {
    // Only processes this.files (VsixManifestBuilder files only)
    Object.keys(this.files).forEach(filePath => {
        if (this.files[filePath].contentType) {
            // Add to Override section
        }
    });
}

After:

private genContentTypesXml(builders: ManifestBuilder[], packageFiles: PackageFiles): Promise<string> {
    // Processes all files from all builders
    Object.keys(packageFiles).forEach(filePath => {
        if (packageFiles[filePath].contentType) {
            // Add to Override section
        }
    });
}

This ensures all package files receive proper Override elements in [Content_Types].xml, regardless of which builder added them.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<issue_title>Linux executables with no file extension are missing from generated [Content_Types].xml manifest</issue_title>
<issue_description>We've encountered this a few times with task extensions that contain an Linux executable that does not have a file extension. Those files are missing from the generated content type mappings file. Files without extensions need to be explicitly entered as an Override element in the [Content_Types].xml file. If that Override is missing, some digital signing tools will remove the files or fail to sign the package in a way that it can be verified later.

Ping me internally for a repro.</issue_description>
