v0.6.3 — Delegation precedence and Ollama Cloud

Ontheia 0.6.3 — Delegation precedence and Ollama Cloud

Delegation now follows a clear order: an explicit task the caller names and
that exists at the agent wins over the agent's default chain, and a named
chain runs bound to the agent instead of that default. A task the caller
named but that does not exist no longer silently runs a different task — it
falls back to the chain and the trace says so. The delegate-to-agent tool
accepts a chain, and the three divergent copies of its definition were
folded into one shared module.

Ollama's hosted cloud endpoint (ollama.com) is detected as OpenAI-compatible
on its own, so tool calling and streaming work for models like kimi-k3:cloud
without a manual flag. The local endpoint keeps going through the private-
host check.

Memory tools gained a way to change an entry's wording without duplicating
it, and the search tool can filter by tag. The Chain Designer opens a chain
straight from the agent accordion, and the documentation is linked from
inside the application.
