feat: update DEF CON 34 firmware to 2.8.0.8adc7c3

[thebentern]

Points the DEF CON 34 edition at the newly published build:
event/defcon34/firmware-2.8.0.8adc7c3 (was 2.8.0.b00d76f).

• version / id / title / zipUrl bumped to 2.8.0.8adc7c3
• Preview-build warning removed from the release notes — this is the real event build, so the notes now open with ## Welcome to DEF CON 34! 💀 exactly like every other edition's do

The slug stays defcon34, so the flasher's derived path event/{slug}/firmware-{version} resolves to the new directory. Verified live before opening: the manifest the flasher fetches (firmware-2.8.0.8adc7c3.json) and a sample device artifact (firmware-heltec-v3-2.8.0.8adc7c3.factory.bin) both return 200 from raw.githubusercontent.com.

Companion PR keeps the API manifest and the flasher's bundled fallback copy in sync.

Note (pre-existing, not changed here): the zipUrl convention — event/{slug}/firmware-{version}.zip — 404s for every edition, since github.io stores these builds as directories rather than a single zip. It's carried forward as-is; worth a separate cleanup if nothing consumes it.

Poem

A bunny hops past firmware bright,
New build numbers shine tonight.
Preview notes tuck out of sight,
The DEF CON record now feels right.
