fix(cli): print registered flags in --help - #352
Conversation
Custom usage printers replaced FlagSet defaults, so expose and relay-server help listed examples and omitted identity-path, relays, api-port, and sni-port. Closes #351

📝 WalkthroughSummary by CodeRabbit
WalkthroughThe change shares CLI flag registration between command execution and usage rendering. Help output now lists fallback defaults, loopback examples, and the ChangesCLI flag help output
Merge Risk: 🔵 Low · up to Help generation can leave the command’s shared output destination pointed at the temporary help writer, causing later usage or parse-error messages to appear in the wrong place. The impact is localized and the PR is otherwise mergeable, but the destination should be restored. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

- Around line 530-537: Update WriteFlagDefaults and the StringFlagEnv
default-registration flow so resolved environment values are not emitted by
fs.PrintDefaults; use non-secret fallback-only defaults or redact sensitive
values while preserving normal help text. Add a regression test covering
WriteFlagDefaults that verifies credentials such as ADMIN_TOKEN and
AWS_SECRET_ACCESS_KEY never appear in the generated output.

Flags were visible after the previous commit, but help still did not map api-port to --relays or name the service ready at log line. See also: #351

Summary
portal expose --helpandrelay-server --helpnow list the flags those commands already parse, and they include a loopback wiring pair plus the ready log line. Before, a cold agent limited to CLI help could not find--identity-path/--api-port, and after flags landed it still could not mapapi-portto--relaysor know that success starts withservice ready at.Defaults are unchanged (
discoverystill defaults true; SNI still defaults 443). The loopback section is additive.Closes #351. Fit: #346 principles 1 and 2.
Validation
