Bundle Visual C++ runtime in Career 1.9 Windows snapshots

[Orinks]

What changed and why

Windows snapshots could fail to start with missing Visual C++ runtime DLLs. Stage the complete official x64 CRT family beside the executable and audit normal and delay-loaded VC dependencies before packaging. Target Career 1.9 as explicitly requested by the owner.

Preserve the synchronized snapshot workflow unchanged to avoid its main/Career equality guard blocking nightly builds. Add a separate Windows runtime packaging workflow for Career PRs and relevant pushes.

What players or maintainers will notice

Portable Windows downloads include the runtime DLLs needed to start without a separate redistributable installer. Incomplete or wrong-architecture runtime sources fail packaging.

Tests and checks run

• Full Python tooling suite rerun on final content: 305 passed, 10 skipped.
• Focused runtime packaging regressions: 13 passed locally and on Windows CI.
• Windows CI staged and audited the actual installed Visual Studio CRT successfully: https://github.com/Orinks/Freight-Fate/actions/runs/34066695564
• Ruff, Python compilation, diff whitespace checks passed; local merge tree matches the tested tree exactly.
• Independent code review found no remaining blockers after correcting the snapshot workflow synchronization issue.
• Clean Windows machine game launch, sound, and screen-reader validation remain release follow-up work recorded in ROADMAP.md; hosted-runner CRT validation does not establish that.

Accessibility impact

Packaging-only change; no gameplay or spoken interface changes. Prevents startup failures before screen-reader support can initialize.
