Crosswire crosswire-v0.14.0

Added

• CI release pipeline (epic #14): dev-channel firmware artifacts on every
  firmware-base push / PR (ci.yml), and a release.yml workflow that builds
  the curated community board set from crosswire-v* tags and publishes a
  GitHub Release (pre-release for -rc*, "Latest" for stable). Curated env set
  in .github/release-envs.txt (72 envs; heltec_v4_repeater_telemetry gated on
  #20). Design of record: docs/architecture/2026-06-06-ci-release-pipeline.md.
  (#15, #16, #17)

Changed

• Reconciled inherited CI workflows: removed 7 dead/superseded
  (pr-build-check, auto-promote, github-pages, the three upstream-tag
  build-*-firmwares, branch-cleanup); kept build-safeboot-firmwares +
  sync-labels-to-board. (#18)
