CI: auto-build and deploy firmware to GitHub Pages on every push to main

Rewrite release-firmware.yml to build the tdeck (NimBLE) env on pushes to
main (versioned as dev-<sha>) and on v* tags. Remove checked-in firmware
binaries from git tracking — CI now generates and deploys them to Pages.
Release creation is conditional on v* tags only.
