feat(launcher): sync release assets from manifest or attachment list (no fixed exe name)

- default files []: resolve sync list from patch-manifest keys, else discover
  release attachments (exclude launcher artifacts).
- Explicit files[] still overrides; strip deprecated Wow-patched.exe on merge.
- listReleaseAttachmentNames + fetchGiteaReleaseRecord helpers.
- Version 1.0.7; README config docs.
