feat: dyndns + secrets setup --plugin (consolidated; supersedes #736 + #737)#740
Merged
Conversation
Supersedes #736 + #737 with lint fixes applied: dyndns/ (T14..T16): - IP-detect multi-source quorum + diff + Update callback + exp-backoff with jitter. 12 tests. cmd/wfctl/secrets_setup_plugin.go (T3+T4): - secrets setup --plugin reads plugin.json required_secrets[], prompts each (masked iff sensitive), writes to chosen GH scope (repo|env|org). 7 tests. Lint fixes vs the original PRs: - dyndns/dyndns.go Run() — replaced empty-branch (SA9003) with explicit `_ = d.Tick(...)` ignoring the error. - dyndns/dyndns.go jitter — math/rand/v2 G404 false-positive silenced with nolint:gosec annotation (decorrelation, not crypto). - dyndns/dyndns.go timeAfter — replaced unlambda wrapper with direct `var timeAfter = time.After`. - cmd/wfctl/secrets.go — hoisted `args[1:]` into a local var to silence gosec G602 (already bounded by outer switch). All tests pass; golangci-lint clean. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Pull request overview
Adds a new dynamic DNS daemon package and extends wfctl secrets setup with a --plugin mode that reads required_secrets[] from a plugin’s plugin.json and prompts the user to set them into GitHub secrets scopes.
Changes:
- Introduces
dyndnspackage with quorum-based public IP detection, update callback, and backoff/jitter behavior (+ unit tests). - Adds
wfctl secrets setup --plugin ...dispatcher and implementation that loadsplugin.jsonrequired secrets and writes them to repo/env/org GitHub secrets. - Adds tests for plugin manifest loading, prompting, and scope routing.
