WIP - Improve CLI

[jveitchmichaelis]

Description

• Split "tasks" into sub scripts for easier organisation
• Improvements to the training script to support many things that we want to do in common situations:
  • Comet/Tensorboard logging, optional
  • Sensible defaults for log directories
  • Defaults for callbacks (image + checkpoints)
• Adds a log directory to the config + schema

WIP:

• Will remove some DINOv3 specifics
• Need to merge better support for resume/fine-tune (see dino/eval branch)

AI-Assisted Development

Some use of Claude Code for assisted testing (e.g. checking it can start training jobs).

• I used AI tools (e.g., GitHub Copilot, ChatGPT, etc.) in developing this PR
• I understand all the code I'm submitting
• I have reviewed and validated all AI-generated code
