docs(website): explain what the skill unlocks, and document config.toml

The agent-native copy described what the skill contains rather than what it
buys you. A new home-page section shows the shape of the request that becomes
possible — describe the outcome, let the agent write the pipeline — and names
the specific knowledge --help cannot carry: which JSON keys a record has, that
exit 4 means widen the query, that a remote path goes back byte-identical,
that --follow never returns.

The install page gains a reference for all nine config.toml settings with
their defaults and an example file, next to the paths that were already there.
The list is the one `config set` accepts, checked against FileConfig::KEYS.
