Start Voice Forge in Train mode.

Read ../voice-forge/SKILL.md (the voice-forge skill next to this one) and follow it. If that path does not resolve, use the installed voice-forge skill by name.
Then read ../voice-forge/references/train.md and run a training round.
If the user gave a word after the command, it is the profile name, for example economics-en. A second word, if any, is the topic or the focus (openings, closings, transitions, data, hard). If the user adds from and a file, link or pasted text, run an own-text round: the passage comes from that text (see Step 2 of train.md).
If no profile was given, pick one as SKILL.md section 2 says.
