v0.4.2

fix(release): make crates publishable + harden winget; bump 0.4.2 (#16)

The v0.4.1 release partially failed. Root-cause fixes:

• crates.io: steamie-core embedded DRM-FREE-GAMES.md via a path escaping
  the crate dir (../../), so cargo publish couldn't package it. Moved the
  file into crates/steamie-core/ and switched to a local include_str path.
  Verified with cargo package -p steamie-core (the isolated-tarball build
  that the normal build/clippy/test gate does NOT exercise).
• winget: build the release-asset URL directly instead of querying the
  GitHub API, which could return the release with an empty assets array
  right after upload (eventual consistency) and fail the job spuriously.

Bumped to 0.4.2 because steamie-api 0.4.1 already published and can't be
republished. (The AUR failure was a malformed AUR_SSH_PRIVATE_KEY secret,
fixed out-of-band by re-setting it from the working key.)
