feat(plugins): add keystore new and import commands to Toolkit
Add picocli subcommands for keystore management in Toolkit.jar: - `keystore new`: generate new keypair and encrypt to keystore file - `keystore import`: import existing private key into keystore file Both commands support: - --password-file for non-interactive password input - --keystore-dir for custom output directory - --json for structured output - Console.readPassword() for no-echo interactive input - Clear error when no TTY available (directs to --password-file) Import reads private key from --key-file or interactive prompt, never from command-line arguments (security: avoids ps/history exposure). Also adds roundtrip property tests (100 random encrypt/decrypt cycles) and cross-implementation compatibility tests to crypto module. Note: jqwik was planned for property testing but replaced with plain JUnit loops due to Gradle dependency verification overhead.
