chore(toolkit): bump for lock-screen artwork off-main crash fix (e672637) [gated on toolkit #198] (#1304)

* chore(toolkit): bump for lock-screen artwork off-main crash fix (e672637)

SURGICAL bump — develop's current toolkit pointer (358f8d3) + ONLY the 14-line
artwork fix (no other toolkit-main delta), so this changes nothing but the crash
fix.

Fixes the toolkit half of the two 3.2.0 audiobook now-playing crashes: the
toolkit's updateLockScreenCoverArtwork built a non-@sendable MPMediaItemArtwork
request handler capturing the UIImage, which MediaPlayer destroys on its own
background queue → block_destroy_helper EXC_BREAKPOINT (Crashlytics e672637).
Mirrors the app-side NowPlayingCoordinator fix (#1218).

Companion crash 4a92d371 (app-side updateNowPlayingInfo) is ALREADY fixed on
develop by #1218 — this closes the remaining toolkit half.

Toolkit fix: ThePalaceProject/ios-audiobooktoolkit surgical branch (cherry-picked
onto develop's pointer). Toolkit main gets the same fix via #198.

* chore(toolkit): re-point submodule at merged toolkit main (#198 → 08f70459)

Toolkit PR #198 (lock-screen artwork off-main block-destroy crash fix, e672637)
merged to ios-audiobooktoolkit main as 08f70459. Re-point the submodule from the
pre-merge branch commit to the merged main SHA so the pin is reachable from
toolkit main (reproducible), completing the gate this PR was blocked on.
