feat: static binary builds and automated release script

Switch reqwest from native-tls (openssl) to rustls-tls for a pure-Rust
TLS stack, enabling fully static musl builds. Add `nix build .#static`
for portable Linux binaries and `scripts/release.sh` for automated
Gitea releases with changelog generation.

-This script runs ALL of the following checks and will fail if any regress:
-1. `cargo check` — no Rust compilation errors
-2. `cargo test` — all Rust tests pass (currently 387)
-3. `cargo build --release` — release binary builds

-**After completing each logical unit of work, commit immediately.** This is NOT optional — every fix, feature, or change MUST be committed right away. Do not let changes accumulate uncommitted across multiple features. Each commit should be a single logical change (one feature, one bugfix, etc.). Use `--no-gpg-sign` flag for all commits.
