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.

Do not merge with a 404 firmware download URL.

The new zipUrl returns HTTP 404, so users cannot download the DEF CON 34 firmware. Publish the ZIP at this path or update zipUrl to the verified working artifact URL; add a link-status check to prevent recurrence.
