feat: add download mirrors and drop legacy install scripts

Browse Source 
Introduce `--mirror` and `DCRUP_MIRROR` so `dcrup` can fetch prebuilt
binaries from multiple CDNs. Default `auto` tries cf → gh → sf → ya
and uses the first successful download.

- dcrup.sh / dcrup.ps1: mirror chain, CLI flag, env override
- remove install.sh / install.ps1 / install_bsd.sh (superseded by dcrup)
- GitHub Actions: upload releases to Cloudflare R2 next to Yandex S3
- docs: README, FAQ, changelog, installation, env vars, contributing

# Changelog # Changelog
## [Unreleased]
### RU
**Добавлено:**
- **Зеркала загрузок в `dcrup`** — `--mirror auto|cf|gh|sf|ya` и `DCRUP_MIRROR`.
По умолчанию `auto`: **cf → gh → sf → ya** (CloudFlare CDN, GitHub, SourceForge, Yandex CDN).
**Удалено:**
- **`install.sh` / `install.ps1` / `install_bsd.sh`** — устарели, заменены `dcrup`.
### EN
**Added:**
- **Download mirrors in `dcrup`** — `--mirror auto|cf|gh|sf|ya` and `DCRUP_MIRROR`.
Default `auto` tries **cf → gh → sf → ya** (CloudFlare CDN, GitHub, SourceForge, Yandex CDN).
**Removed:**
- **`install.sh` / `install.ps1` / `install_bsd.sh`** — superseded by `dcrup`.

## Unreleased
- **Download mirrors in `dcrup`** — `--mirror auto|cf|gh|sf|ya` and `DCRUP_MIRROR`.
Default `auto` tries **cf → gh → sf → ya** (CloudFlare CDN, GitHub, SourceForge, Yandex CDN).
- **Removed `install.sh` / `install.ps1` / `install_bsd.sh`** — superseded by `dcrup`.
