Summary

Fixes #130 by preserving terminal input when PTY command delivery is not confirmed.

Changes

• Use the checked PTY send result before recording or clearing input.
• Preserve input and report whether delivery may have been partial or was not confirmed.
• Add regression coverage for partial rejection and accepted sends.
• Document the fix in the unreleased changelog.

Validation

• ./gradlew :app:testDebugUnitTest --tests com.hermesgadget.talaria.feature.terminal.TerminalViewModelTest
• ./gradlew :app:lintDebug
• ./gradlew :app:assembleDebug

Compatibility and limitations

The full unit-test task was attempted; unrelated Robolectric baseline failures remain in the local SDK/test environment.
