feat: add emoji factory for emoji config

[SamuNatsu]

close #3515

[Copilot]

Pull request overview

Adds an “emoji factory” capability to the client emoji configuration pipeline, enabling emoji configs to be provided as functions (sync/async) that can return either a single WalineEmojiInfo or a prebuilt { tabs, map } structure—supporting more flexible/custom emoji package setups (per #3515).

Changes:

• Extend getEmojisInfo() to accept emoji factories and merge returned { tabs, map } into the final emoji config.
• Introduce the WalineEmojiFactory type and propagate it through public option/prop typings.
• Minor formatting adjustment in word limit normalization.

LGTM, but maybe some small refactor. Let me enjoy the weekend and look deep into it Monday
