Root cause of "malformed request":
- buildIntentUrl() was calling encodeURIComponent() on ALL values including
callbackUrl, which was ALREADY a full URL with special chars
- This double-encoded the callbackUrl, arriving at Amber as garbage
- The intent: wrapper format was also unnecessary
Fix: back to clean nostrsigner: format per NIP-55 spec
- Only callbackUrl gets encodeURIComponent (once)
- All other params are plain query string values
- Matches exactly what NIP-55 spec shows in its example code

- release_notes must be a file path for zsp, not inline YAML text
- add release-notes.txt with v1.0.26 changelog
- sync package.json version to 1.0.26 to match APK versionName
