feat(workflows): file release-notes action-item issues from update-awf-version (#593)

When the dependency version updater bumps AWF_VERSION, MCPG_VERSION, or

COPILOT_CLI_VERSION, it now also analyzes the upstream release notes

between the previously-pinned and new latest versions and files a single

per-dependency '[deps-release-notes] <dep> v<latest> action items' issue

summarizing breaking changes, security fixes, notable adoptable features,

and deprecations. Routine releases (patch fixes, internal refactors, etc.)

produce no issue. Dedup is per-dep via title prefix; older superseded

issues are closed via a new close-issue safe output. Bump PR bodies now

cross-link to the expected companion issue title.
