fix(windows): render packaged app under strict CSP

[RebelliousSmile]

Summary

• precompile Vue I18n locale messages for the packaged CSP
• align the precompiler with Vue I18n 9 and emit AOT functions (jitCompilation: false)
• allow the Tauri IPC custom protocol in connect-src
• release manifests as 0.3.2
• add packaged security configuration regression coverage

Verification

• pnpm test: 30 files, 362 tests passed
• cargo test: 3 tests passed
• pnpm build: passed
• pnpm tauri build: MSI and NSIS produced
• packaged WebView2 smoke test: login form rendered (3 inputs, 2 buttons), zero console/CSP errors
• bundle scan: no new Function or unsafe-eval

Existing lint debt

pnpm lint reports 400 pre-existing Vue warnings and no errors; this bug-fix diff introduces no lint warning.
