Agendula: repin floret-kit to shared main, Gradle 9.8 toolchain (#44)

Moves the floret-kit submodule from v0.4.0 (db4be68) to floret-kit main (8b33635). The kit's per-app branches were folded back into main in jlmakiola/floret-kit#11, so agendula now tracks the same line as calendula, clockula and vouch. The kit adds core-prefs, core-di, CollapsingScaffold FAB/no-back slots, the glance module, LocaleManager on API 33+ and a dependency bump; nothing existing is removed.

floret-kit main requires Gradle >= 9.6 in the consuming build, so this also bumps Gradle 9.5.1 → 9.8.0, AGP 9.2.1 → 9.4.1 and Kotlin 2.3.21 → 2.4.20. Hilt 2.60.1 / KSP 2.3.11 were already new enough. No source changes.
