License the project; add root README, website, and parked release CI
- Code: GPL-3.0-or-later (LICENSE, SPDX headers on all .kt/.aidl). Specs in docs/: CC-BY-4.0 (docs/LICENSE). Rationale in build-status.md; server decided GPL (not AGPL). - Root README for the public repo. - web/: Cloudflare Worker site for echo-lot.app. /apk resolves the newest APK from the Gitea latest-release API at request time (edge-cached 5 min), so tagging a release is the only publish step. /fdroid, /source, and a manual DOWNLOAD_URL fallback are wrangler vars. - .gitea/workflows/release.yml: tag-driven (v*) signed semver APK builds for the future production app in echolot-app/. Parked; the prober is deliberately not CI-built. - Fix UserService.kt: drop the explicit secondary constructor that conflicted with the implicit primary (never compiled before — first local build caught it). Prober now builds: :app:assembleDebug OK. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
