docs: replace the decommissioned ollama.ltms.dev host

A page audit found the dead host still named in four places outside the wiki.
ollama.ltms.dev no longer exists; the one front door is llm.ltms.dev, and the
path differs by backend - /anthropic for claude-code, /v1 for opencode.
Anyone following README.md today points a member at nothing.

README.md also now links the new wiki chapter 13, the operator guide, since
the README's own next step used to be the never-written Setup page.

Not touched: SubscriptionGuard.java:14 still names ollama.ltms.dev, but only
in a javadoc line describing the Stage-1 example allowlist. It is a comment
about history, not a live default, so it stays until that class is next
edited for its own reasons.
