feat: tools refactor, started work on subagent

Related issues:

• Subagent tool & smarter ways to handle context #61
• Improve planning for complex tasks #75

Questions

• Should these subagents be ran in the background? Waking the main agent when done?

From my notes

I should add a function that serves as a wrapper to chat, making a prompt that makes the agent give a JSON return value.

• Then give the LLM a tool to spawn subagents and check on their status.
• Give it a sleep/await tool to wait for one or more tasks to complete
  • Feels like I could just prompt it to do this via the reply by providing examples
• Could also give the sub-LLM a tool to update the status.
  • Low value, but would be nice UX with an indicator

Ended up refactoring how tools are defined and registered, including how their prompts are constructed from their tool specs. Tools are extremely modular now.

Hoping to finally get this merged
