v0.1.0

The first release of AIHawk as a package. Before this, the repository was
documentation for an MCP server you installed into somebody else's client. Now it
is the thing itself.

```bash
uvx aihawk ui --openrouter-key sk-or-...
```

Then open `http://127.0.0.1:8765`: the conversation on the left, the live browser
on the right. One command, one key, no client to install and nothing else to run.

`aihawk do "..."` is the same machinery with no page and an answer on stdout, for
scripts and cron. Literally the same: there is one loop in the package and one
call to the model, and the narration is a parameter rather than a mode.

**Without a key it still starts.** What answers is a placeholder that understands
five literal commands - `go`, `read`, `click`, `type`, `tab`, `shot` - which is
enough to see the interface work and to tell a browser problem from a model
problem without spending anything. It is not a fallback; it is how most of this
release was tested.

**Nothing here has a privileged path to the browser.** The interface talks to
[invisible-playwright-mcp](https://github.com/feder-cr/invisible-playwright-mcp)
over MCP, using the same fourteen tools any other client gets. That is the reason
to trust the tools are sufficient to build on: the flagship interface is a client
of them.

**The key never reaches the browser process.** It is stripped from the
environment the engine is started with, and a test fails if that stops being
true.

Requires `invisible-playwright-mcp` 0.9.0 or newer. The tab strip needs
`session_list_pages` to return id, title, url and which tab is active - four
fields its description had always promised and, until 0.9.0, had never returned.
