chore: add ktlint to devenv format/lint and CI lint pipeline

##72 by @ifiokjr

Summary #

Adds Kotlin lint/format support to the repository devenv workflows and ensures CI runs those checks.

What changed #

Added ktlint to packages in devenv.nix.
Updated fix:format to run Kotlin formatting via:
- ktlint --relative --format on tracked *.kt and *.kts files.
Added a new lint:kotlin script that runs:
- ktlint --relative on tracked Kotlin files.
Updated lint:all to include lint:kotlin so Kotlin linting is part of the standard CI lint command.
Updated CI lint step label to explicitly indicate ktlint is included.

Why #

The repo already linted and formatted Dart/Markdown/JSON/YAML paths, but Kotlin files were not covered by the same developer and CI workflows. This aligns Kotlin quality gates with the rest of the codebase.

Validation #

dprint check .github/workflows/ci.yml
Structural verification of devenv.nix script blocks for:
- fix:format
- lint:kotlin
- lint:all

chore: add flutter example app for mobile wallet adapter manual testing

Summary #

Adds a runnable Flutter Android example app under packages/solana_kit_mobile_wallet_adapter/example/ for manual Mobile Wallet Adapter (MWA) testing on device/emulator.

What changed #

Scaffolded a full Flutter Android example app for solana_kit_mobile_wallet_adapter.
Added manual-test UI flows for:
- Wallet endpoint detection
- authorize
- getCapabilities
- signMessages
- deauthorize
Added example/README.md with setup instructions and mock wallet installation guidance based on Solana Mobile docs.
Updated package README with a dedicated "Manual testing app" section linking to the new example and setup guide.

Why #

The previous example was not a runnable Flutter app for end-to-end manual testing with real/emulated wallets. This adds a practical test harness for validating adapter behavior in development.

Validation #

flutter pub get (example app)
flutter analyze (example app)
flutter test (example app)
devenv shell -- docs:check
