* fix(cli): honor PASEO_PASSWORD env var (fix#776)
The CLI only extracted passwords from `tcp://host?password=` URIs, so
`PASEO_PASSWORD=xxxx paseo ls` connected without auth and was rejected
by the daemon with "Password required". Fall back to the env var when
the host (TCP or otherwise) carries no password.
* docs: document PASEO_PASSWORD env var as a CLI auth source
Pairs with the CLI fix in this branch — the "Connecting with a password"
section now lists both the tcp URI query and the env-var fallback, with
their precedence. Also clarify the dual role (daemon vs CLI) of
PASEO_PASSWORD in the env var reference.
