fix: resumeInfinity/onresume interaction

[tuncayuk]

1. Change resumeInfinity to reset the existing timeout instead of calling clear() when a timer is present

2. Introduce resumeFromKeepAlive guard so keep-alive resume() calls don’t recursively trigger resumeInfinity

Key changes for consumers:

a. You can now pass enableUtteranceKeepAlive as a configuration parameter:

this.$announcer.configure({ enableUtteranceKeepAlive: false });
this.$announcer.enable();

b. You can cancel previous utterances via an option on speak:

this.$announcer.speak(utterance, 'off', { cancelPrevious: true });
