v0.1.1 — bare uvx invocation, generated tool docs

The wheel now provides an executable named after the distribution, so uvx yet-another-agentic-chat works with no --from; the yaac command remains for local use. The MCP tool reference (docs/tools.md) is now generated from the live server's tool registry, the tool surface identifies itself as YAAC (Yet Another Agentic Chat) so "connect to yaac" resolves in any client, and the README leads with what sets YAAC apart: unrelated sessions in unrelated clients meeting on one machine, with configuration that rounds to zero.
