feat(core): add configurable text input strategies

[quanruzhuoxiu]

Summary

• add inputStrategy: 'legacy' | 'sequential' | 'bulk' to aiInput, YAML input actions, and platform-level defaults
• keep legacy as the compatibility-safe default while allowing explicit Unicode code-point input or one-operation bulk input
• support Web, Chrome Extension/Bridge, Android, iOS, HarmonyOS, local Computer, and RDP backends
• make Web bulk replacement select the existing value and use insertText, producing one insertion event instead of clear-plus-character events
• validate layered action/platform options before mutating an input field and reject invalid delay combinations with actionable errors
• document the behavior in English and Chinese
