Jean-Luc Makiola 955d47ef12 chore: draw shared code from floret-kit (fresh re-migration onto current main)
Supersedes the stale chore/floret-kit-core-time branch: re-applies the
floret-kit migration on top of current main (122 commits ahead of the old
branch's base), pinning the kit at the multi-value-reminders + pinned-picker HEAD.

- Submodule + composite build (includeBuild), 6 module deps, CI submodules:
  recursive, reproducible-release scan extended to the kit, F-Droid recipe.
- Deletes the inline copies now owned by the kit (GroupedList, Picker scaffolds,
  InlineTextField, OptionCard, DialogControls, CrashReporter + dialog/submit,
  OnboardingScaffold, AppLanguage, TimeBridge, ReorderableColumn, DebugRibbon)
  and redraws them from components/identity/core-crash/core-locale/core-time.
- Reminder overrides drawn from core-reminders (multi-value ReminderOverride +
  codec); Calendula keeps its app-specific bits (all-day resolution, labels,
  presets, the multi-select ReminderDefaultPicker, its own CrashReportActivity).
- Theme draws FloretExpressiveTheme while keeping the user-typography param.

Build pending (deferred): run ./gradlew :app:compileDebugKotlin with ANDROID_HOME
(or floret-kit/local.properties) set.

# Reproducibility guard for the official F-Droid repo (de.jeanlucmakiola.calendula).
#
# F-Droid only republishes OUR signed binary if a from-source build reproduces it
# byte-for-byte and the binary carries no extra signing blocks. If any invariant
# below regresses, the official repo silently stalls on the last good version
# (fails safe — but you'd be stuck on an old release without noticing). So fail
# loudly here, on every PR.
#
# Each invariant was learned from a real fdroiddata CI rejection (see
# docs/fdroid-official/ and the v2.7.3 -> v2.7.5 history):
# 1. vcsInfo { include = false } — else AGP embeds env-dependent git
# metadata (META-INF/version-control-info.textproto) -> not reproducible.
# 2. no foojay toolchain resolver — F-Droid's offline source scanner
# rejects org.gradle.toolchains.foojay-resolver (it can fetch a JDK over
# the network at build time).
# 3. dependenciesInfo { includeInApk = false } — else AGP embeds a "Dependency
# metadata" block (id 0x504b4453) in the APK Signing Block, which F-Droid's
# binary scanner rejects as an extra signing block.
