Documentation

• The command reference and alias tables now cover every command - Every pcli2 ... example in the README and the documentation site was checked against the binary's own help: all commands and flags exist. Twelve commands were missing from the README reference (asset similarity, config get path, config validate, user list, user get, cache clear, doctor and the environment commands), the alias tables lacked a dozen aliases, the feature lists still described resume as downloads-only and omitted the scripting flags and diagnostics, and pcli2 config get (a command group) was shown where config get path was meant. No code changes.
