fix(lint): resolve E410 doc style and E415 missing pp across packages
Fix 64 documentation style issues: add trailing periods, fix [name] format
mismatches, and correct arg count mismatches in doc comments. Add pp
pretty-printers to 7 modules (block_map, standard_site_api, tangled_api,
xrpc_auth_client, xrpc_client, xrpc_cred, block).
