[feature] Anaconda AI support

[AlbertDeFusco]

Here in this PR a small-ish refactor of AI Clients is provided to streamline discovering models and running the agentic response loop.

Since many LLM services provide OpenAI-like API endpoints the RuntOpenAIClient can now be used as a base class as-needed. Important factors are

• setting custom provider name in subclasses
• setting env var prefixes in subclasses
• setting default configuration parameters, which can be overridden with a config dictionary

More could be done to have ollama and openai-like clients share a common ancestor for essential members like .discoverAiModels, .generateAgenticResponse and others that are essential to external operation, but I'll leave that for another PR.

Finally, the RUNT_API_KEY (for anaconda idp) can now be used to request chat/completions from an Anaconda endpoint. This means that user need not set any other AI keys or have ollama running to use the AI agent.

@rgbkrk , I've added reading the version from deno.json, but I'm concerned that it would only work when executing from a clone of the repo and not on the published package. Is it possible to include the deno.json in the published package? Or would there be a better approach.

5 | import pkgInfo from "../lib/deno.json" with { type: "json" };
  |                     ^^^^^^^^^^^^^^^^^^ the specifier
  | 
  = hint: replace the relative import with a bare specifier that imports from the other package by name and optionally an export (ex. "@runt/lib")

What do you think about adding a function here to write the version string to something like packages/lib/version.ts that gets updated when versions are bumped?

I've added VERSION attribute to @runt/lib and the version.json is updated by the bumper script
