fix: build Linux Python wheels with vendored OpenSSL (manylinux + musllinux) (#327 )

Fixes the Linux Python wheel build that broke the `0.9.3` release (and would have broken `0.9.4`), and adds a CI guard so it cannot regress silently. ### Root cause The `live-binance` data layer links `native-tls` -> `openssl-sys`, which needs OpenSSL at build time. Neither wheel container provides it: - **manylinux** ships no OpenSSL headers, and - **musllinux** cross-compiles against a musl sysroot that has no OpenSSL at all, so installing a host package (`yum`/`apk`) cannot reach the cross target. The 3-OS Python CI jobs build natively on the runner, which already has system OpenSSL, so CI stayed green while the release container build failed. ### Fix - New opt-in **`vendored-tls`** feature on `wickra-data` and the Python binding: enables `native-tls/vendored`, compiling OpenSSL from source and linking it statically. No system OpenSSL needed on either libc. No-op on macOS/Windows (Security.framework / SChannel — `openssl-sys` is never in the graph there). - `release.yml` builds the Linux wheels with `--features vendored-tls` (replaces the manylinux-only `before-script-linux` header install, which could not fix the musllinux cross build). - CI gains a **`manylinux` + `musllinux` container build-smoke** matrix job, so both container builds run on every PR. This PR's own CI is the proof the fix works before any release re-attempt. ### Notes - No version bump: `0.9.4` published nowhere (the release run was cancelled before any publish job ran), so this lands on `0.9.4` and the tag is re-pointed at the fixed commit. - Adds checks to `ci.yml` (the smoke job is now a 2-entry matrix).

 ## [Unreleased]

+## [0.9.4] - 2026-06-17
+
+Packaging fix for the `0.9.3` data layer. The library is identical to `0.9.3` on
+every platform that already published; the only additions are an opt-in
+`vendored-tls` build feature and the Linux Python wheels, which `0.9.3` could not
+build.
+
+### Fixed
+- **Linux Python wheels (`manylinux` / `musllinux`) now build.** The `live-binance`
+  data layer links `native-tls` -> `openssl-sys`, which needs OpenSSL at build
+  time. The `manylinux` wheel containers ship no OpenSSL headers and the
+  `musllinux` build cross-compiles against a musl sysroot that has no OpenSSL at
+  all, so the wheels failed to compile. The Linux wheels are now built with a new
+  opt-in `vendored-tls` feature that compiles OpenSSL from source and links it
+  statically (no system OpenSSL required, on either libc). The native macOS and
+  Windows wheels were unaffected (Security.framework / SChannel). As a result
+  `0.9.3` shipped to crates.io, Maven Central, NuGet, and npm but not to PyPI;
+  PyPI publishes starting with `0.9.4`.
+
+### Added
+- **`vendored-tls` feature** on `wickra-data` (and the Python binding): builds the
+  `live-binance` TLS stack against a statically compiled OpenSSL. Off by default;
+  used by the release wheels and exercised on every PR by a `manylinux` /
+  `musllinux` container build-smoke CI job.
