docs(release): add 2.21.1 notes (Trusted Publishing pipeline) (#252)

docs(release): add 2.21.0 notes (ContextProvider.context_type) (#245)

Curated notes for the 2.21.0 stable tag — release.yml requires
planning/releases/<tag>.md before it will publish. 2.20.0 already shipped
get_named_providers (#242) without context_type (#244), so the public
context_type attribute ships as 2.21.0.

feat: add Group.get_named_providers() (#242)

Add Group.get_named_providers() (MRO-aware name->provider dict); reimplement get_providers() on top of it. Fixes the KeyError when autowiring a Group that inherits providers. Unblocks modern-di-litestar 2.20.0 consumer.

docs(release): add 2.19.2 notes (#234)

Docs (#231 roadmap, #232 comparison pages) + tag-driven release tooling
(#233). No modern_di/ source change since 2.19.1 — the wheel is functionally
identical; notes say so explicitly.

docs(release): add 2.19.1 notes + a release-notes template

2.19.1 is internal-only (WiringPlan, inline error messages, suggester — no
behavior change — plus richer PyPI metadata). Also adds _templates/release.md
(loose: title + optional sections) so future releases don't copy the last one.
