v0.68.10

Claude Code: the repository is now a plugin marketplace as well as a plugin
(`.claude-plugin/marketplace.json`, one entry, source `./`), so the README
teaches `claude plugin marketplace add feder-cr/AIHawk` and `claude plugin
install aihawk@feder-cr` where it taught `claude mcp add`. The plugin delivers
the server and the setup skill, and Claude Code counts it as an installation
of this plugin; a hand-registered server was counted by nobody. Measured: the
real-install test builds its throwaway marketplace from the shipped file with
only the name changed, and the client reports MCP servers (1), Skills (1).
`claude plugin validate .` passes without warnings.

Gemini CLI: `gemini extensions install https://github.com/feder-cr/AIHawk`
where the README taught `gemini mcp add`. The gallery had indexed the
extension for a week; the README was sending people the other way. Codex is
unchanged.

The marketplace name is declared in one file. `marketplace_findings` holds the
README's install line to it, and the fifth check of check_content.py now reads
the client lines from the README too: six pages went on teaching the old
lines with the gate green, because it read only the installer lines. A page
repeats the README's line, names the route bare in prose, or says nothing;
three mutations and two clean cases in the selftest. A plugin id
(`aihawk@...`) is no longer read as the launcher slot.

0.68.10, because the comment in server.py that explains why the server is
named `stealth` cited the README's line, which moved.

The engine fetch stays a step the person runs and watches, in the README's
block or when a browser tool says the engine is missing; nothing here makes
the server download it on its own.
