fix: preserve YAML runtime modules in desktop packages

[EF1874]

Summary

• restore only yaml/dist/doc/*.js after the generic third-party docs exclusion in all desktop builder variants
• keep macOS runtime pruning from deleting YAML's runtime Document module
• exclude third-party source maps so the fix reduces rather than increases package size
• fail Windows/macOS packaging when any packaged YAML copy lacks required Document runtime modules

Verification

• packaged archive: 4 composer copies, 4 directives copies, 4 Document copies, 0 node_modules source maps
• packaged Memmy.exe loaded YAML from app.asar and parsed a document successfully
• required native runtime DLL/Node addon/migrations artifacts remain present
• app.asar: 964,159,678 -> 761,047,617 bytes (-203,112,061)
• installer: 299,242,822 -> 272,922,035 bytes (-26,320,787)
• packaged-runtime-boundary tests: 49 passed
• full workspace typecheck passed
• Windows and macOS packaging shell syntax checks passed
• final review found no Critical or Important issues
