v1.1.1: accounts.googl.com in SNI pool + mipsel-softfloat lands green (#43)

SNI rotation pool gains `accounts.googl.com` (issue #42). Reporter
confirmed it passes DPI on Samantel and MCI — Iranian carriers that
selectively block some of the longer google.com subdomain SNIs.
`googl.com` is a Google-owned redirect alias served off the same GFE
pool, so the TLS handshake works against `google_ip:443` without
extra plumbing; we just present the name in the ClientHello for
fingerprint diversity. Mirrored into the Android default pool too.

The mipsel-softfloat target finally builds green in CI — two earlier
bugs that compounded: messense doesn't publish a `:mipsel-musl-softfloat`
image tag (fixed in main earlier by using `mipsel-musl` +
`RUSTFLAGS=-C target-feature=+soft-float` + `-Z build-std`), and the
pre-installed nightly in that image has a broken component state
that rustup can't upgrade in place (fixed by uninstalling nightly
first). Both fixes are in the tagged commit this time. Closes
issue #26.

Previous issues addressed in v1.1.0 that this release documents the
closing of:
  - issue #28: "egui_glow requires opengl 2.0+" on old Windows /
    RDP / VMs — fixed via dual glow+wgpu compile + MHRV_RENDERER
    env var + run.bat auto-retry.
  - issue #37: connection-mode picker (VPN/TUN vs Proxy-only) so
    users who already run another VPN can still use mhrv-rs as a
    per-app HTTP/SOCKS5 proxy.

Version bump: 1.1.0 → 1.1.1 (versionCode 110 → 111).
