Add Windows Package Manager (Winget) distribution support

[Copilot]

Enables distribution via winget install ScottHanselman.WindowsEdgeLight once submitted to microsoft/winget-pkgs.

Manifest Files

• Created v1.10.0 schema manifests in manifests/s/ScottHanselman/WindowsEdgeLight/0.6.0/
• Configured as portable app (zip → exe) supporting x64 and ARM64
• Template includes placeholder SHA256 hashes with inline comments

Automation

update-winget-manifest.ps1: Downloads release artifacts, calculates hashes, generates manifests, validates against placeholders

.\update-winget-manifest.ps1 -Version "0.7.0"
# Outputs: 3 manifest files with correct SHA256 hashes

Documentation

• docs/WINGET.md: Submission methods (WingetCreate, manual, YamlCreate)
• docs/WINGET_AUTOMATION.md: GitHub Actions workflows for auto-submission
• WINGET_QUICKSTART.md: Maintainer quick reference

Updates

• README.md: Added Winget as installation Option 1
• .gitignore: Excludes temp/ and *.tmp from manifest script

# Method 1: Auto-submit with WingetCreate
wingetcreate update ScottHanselman.WindowsEdgeLight \
  --urls <x64-url> <arm64-url> \

# Method 2: Generate locally, submit manually

Triage note: This Winget manifest/automation PR looks useful but needs review before merging. Key questions: Are the manifest templates correct for our current release structure? Do the SHA256 placeholder hashes get updated by the script? Leaving open for review.
