docs(readme): update in-session examples to match the real hook output

The showcase and Quickstart blocks used a stale "⚡ handled by token-ninja"
banner, made-up rule ids (git-branch-current, git-log-recent, port-usage,
npm-test), and rough token estimates. They also showed conversational NL
prompts being intercepted, which the UserPromptSubmit hook rejects under
--strict mode.

Refresh both blocks with real literal commands users actually type into
Claude Code, the hook's actual suppression banner ("⚡ token-ninja handled
locally (<rule_id>) · saved ~N tokens"), and token-saved numbers captured
from `ninja route --strict` on this repo.
