- loader: guard cfg == nil in Load() to prevent nil-pointer dereference on
cfg.Log / cfg.TLS access.
- loader: defer logger.SetDefault and parsing.SetDefaultTLSConfig until
after register() succeeds, so a failed reload does not leave global
state (logger, default TLS) pointing at the new config while components
remain from the old config.
- loader: extract registerGroup[T] helper to eliminate repeated
unregister-then-register boilerplate. Entries are parsed and collected
before unregistering; a parse error now preserves the previous group
(old code unregistered first, then parsed, leaving an empty registry on
parse failure).
- hop: move cfg.SockOpts.Mark extraction outside the cfg.Metadata != nil
block so the socket mark is read even when hop-level metadata is absent.
- hop: fix copy-paste error in netns inheritance: v.Name was incorrectly
stored as MDKeyNetns instead of v.Netns (introduced in f71351f).
