Pull request overview

This PR implements a speaker speed setting feature for the TTS system, allowing users to adjust the playback speed of text-to-speech audio. The feature adds a new /tts speed <value> command that accepts values from 50 to 200 (representing 0.5x to 2.0x speed), with a default of 100 (1.0x speed).

Changes:

• Added SpeedScale field to TTSPersonalSetting model to store per-user speed preferences
• Extended the VoiceVox API client's Synthesize method to accept and apply speed scale parameter
• Implemented new /tts speed subcommand with validation and user feedback
• Updated help documentation to include the new speed command

The validation check at lines 35-54 is redundant because Discord already enforces these constraints through the MinValue and MaxValue options defined at lines 23-24. This validation will never trigger unless Discord's validation fails.

Consider removing this redundant validation or at least documenting why it's needed as a defensive check.

おそらくはdb.goのSetupDBにこの記述がいる。

	db.Migrator().DropColumn(&model.TTSPersonalSetting{}, "speaker_seed")
	db.Migrator().DropColumn(&model.TTSPersonalSetting{}, "speaker_pitch")
