fix: repair UTF-8 BOM and mojibake introduced in the v1.1.6 bump

The previous commit bumped the version using PowerShell Set-Content, which in
Windows PowerShell 5.1 writes UTF-8 WITH a BOM and re-encodes content read by
Get-Content -Raw under the wrong codepage. Two files were damaged:

- manifest.json gained a leading BOM. Python json.loads rejects a BOM, so this
  could have prevented the integration loading entirely for anyone installing
  v1.1.6.
- README.md gained a BOM plus mojibake throughout, with every non-ASCII glyph
  mangled (emoji and em dashes).

Restored both from the pre-bump commit and re-applied the version change with an
encoding-safe edit. Verified the only difference from the clean state is the two
version strings, and that manifest.json parses.
