Teknium d509ab10d7 fix(providers): lazy provider headers stay a real dict for plugin overrides ...

Review finding (P2, #144640): LazyHeaders was a read-only Mapping, so a
user provider override doing get_provider_profile('gmi').default_headers.copy()
(or |, update, json.dumps, ==) raised AttributeError and the provider
disappeared, in-process and under plugins.isolation: host.

LazyHeaders is now a dict subclass that stores every key up front and
resolves callable values (the release-carrying User-Agent) on first value
read. Every value-reading/mutating method resolves first; __iter__ is
overridden so dict(x)/{**x}/f(**x) leave CPython's raw-storage fast path;
json.dumps takes items() because the stored keys make it non-empty.
.copy()/|/copy/pickle yield plain resolved dicts. Importing provider plugins
still runs no git. The plugin-host Mapping materialization is gone: encode()
reads a dict subclass through items(), which resolves.
