release: v1.6.2

[schloerke]

Summary

Release candidate branch for py-shiny v1.6.2.

Changelog

Bug fixes

• Adapted py-shiny to the htmltools 0.7.0 sibling-classes refactor: removed Tag[TagNode] / TagList[TagNode] type arguments and redundant casts that no longer type-check against the new htmltools. No runtime behavior change. (fix: adapt to htmltools sibling-classes refactor (#116) #2244)
• Bumped lodash/lodash-es to 4.18.1 in the js-react template lockfile for CVE-2025-13465. (bump lodash for CVE-2025-13465 #2233)
• Fixed render.DataGrid() column headers and hovered rows not adapting to dark mode when ui.input_dark_mode() is enabled. (ui.input_dark_mode() in combination with @render.data_frame and render.DataGrid() is faulty #1635)

Test plan

• CI passes
• Shinylive examples pass against py-shiny docs site
• No additional commits land on this branch before squash-merge

Once CI is green, squash-merge → tag v1.6.2 on main → publish GH Release titled shiny 1.6.2.
