#144 feat: add Android keyboard status and dismiss command

Summary

Add a new keyboard command for Android so flows can detect and dismiss the soft keyboard without dropping to raw ADB (issue #102 + comment use case).

• Adds keyboard status|get|dismiss
• Wires command through daemon session/selector flow (active session or explicit target selectors)
• Implements Android backend via dumpsys input_method parsing + best-effort input type classification and reliable dismiss
• Adds unit coverage for capabilities, args/help, session handling, and Android backend behavior
• Updates README, docs, and skill references for the new command

Touched files: 13.
Scope expansion beyond initial command family: No functional scope expansion beyond the new keyboard command path; remaining edits are command registration, tests, and docs.
