android: bump AndroidX/Compose dependency versions

Modernizes the stale library pins in libs.versions.toml against the
already-current agp/kotlin toolchain:

- composeBom 2024.09.00 -> 2026.06.01 (Material3 1.3.x -> current)
- activityCompose 1.8.0 -> 1.13.0
- navigationCompose 2.8.5 -> 2.9.8
- lifecycleRuntimeKtx 2.8.7 -> 2.10.0 (2.11.0 needs compileSdk 37, past
  what AGP 9.1.0 supports; held one minor back)
- coreKtx 1.10.1 -> 1.18.0 (1.19.0 has the same compileSdk-37 issue)
- workRuntimeKtx 2.10.1 -> 2.11.2
- espressoCore 3.5.1 -> 3.7.0, junitVersion (androidx.test.ext) 1.1.5 -> 1.3.0

compileSdk/targetSdk bumped 35 -> 36 to satisfy activity/activity-compose's
minimum. Verified with build, gradlew test, lint-kotlin, and
fmt-kotlin-check per the TODO's verification steps; removes the TODO.md
entry.

Compose 1.7->current and Material3 1.3->current introduced deprecation
warnings (old TabRow, MenuAnchorType, LocalClipboardManager) across several
screens -- these still compile and work, left as follow-up cleanup rather
than folded into this bump.

-### Modernize the Android dependency versions (Compose BOM and the AndroidX cluster)
-- **Description** (added 2026-08-05): `android/gradle/libs.versions.toml` has a
-  current *build toolchain* pinned against a stale *library* set. `agp = "9.1.0"`
-  and `kotlin = "2.2.10"` are recent; everything they compile is not:
-
-  | Pin | Vintage |
-  |---|---|
-  | `composeBom = "2024.09.00"` | Sept 2024 (Material3 1.3.x) |
-  | `lifecycleRuntimeKtx = "2.8.7"`, `navigationCompose = "2.8.5"` | late 2024 |
-  | `activityCompose = "1.8.0"` | Oct 2023 |
-  | `coreKtx = "1.10.1"` | May 2023 |
-  | `espressoCore = "3.5.1"`, `junitVersion = "1.1.5"` | 2022–23 |

-- **Why it isn't already broken**: the Compose compiler is versioned with Kotlin
-  now (the `kotlin-compose` plugin), so a current compiler against a two-year-old
-  Compose runtime keeps working rather than failing loudly. That is exactly why it
-  drifted this far unnoticed.
-- **Why it matters**: two years of Compose/Material3 fixes and APIs are being
-  left on the table, and the gap only gets more expensive to close. The concrete
-  near-term cost is in `docs/command-palette-and-search.md` §7.2: the shared
-  Android search bar has to target Material3 1.3's older `SearchBar`
-  (`query`/`active`/`onActiveChange`) rather than the `inputField`/`expanded` API
-  that supersedes it, purely because of what is pinned.
-- **Details**: bump the AndroidX cluster together, not just the BOM — leaving
-  `activityCompose` on 1.8.0 (Oct 2023) under a current Compose runtime keeps the
-  oldest pin in place and defeats the point. Expect real behavior changes across
-  Compose 1.7 → current and Material3 1.3 → current, affecting every screen; this
-  wants to be its own change with its own verification pass, **not** folded into
-  feature work.
-- **Verification is fully available without a local Android Studio install**:
-  the flake runs Gradle inside the devShell rather than a sealed derivation, so
-  dependency resolution is an ordinary network Gradle resolve — there is no
-  vendored dependency hash to regenerate for a version bump. `just
-  build-android-nix` builds the APK, and `nix develop --command just gradlew
-  test` / `... just lint-kotlin` / `... just fmt-kotlin-check` cover unit tests,
-  detekt, and formatting. A bump should be checked against all four, since the
-  Compose/Material3 jump is expected to move behavior across every screen.
-- **Depends on**: nothing. Should land *before* the Android half of
-  `docs/command-palette-and-search.md` (its §9 step 5), so §7.2 can target the
-  current `SearchBar` API instead of the deprecated one.
