Deepgram CLI v0.3.3

Deepgram CLI v0.3.3 lets you play generated speech straight from dg speak. Add --play to send audio to ffplay, afplay, paplay, or aplay, and combine it with -o to save and play in one command. Use --list-voices to see the available voices and their languages.

The release also changes dg skills to install Deepgram skills v1.7.0 from a pinned, hash-checked bundle. Installation and removal affect only skill folders the CLI owns; upgrade cleanup removes only files it can prove an earlier 0.3.x release wrote.
