Fix reproducible Windows release packaging

[gh615280-maker]

Root cause

The v0.2.0 tag release run checked out almost all text files as CRLF on Windows, while EditorConfig and Prettier require LF. The release workflow also passed relative paths to an audit that requires absolute paths and only collected the two standard installers although v0.2.0 needs standard and offline packages.

Fix

• enforce LF for auto-detected text files in .gitattributes
• run the formatting gate in the Windows acceptance job
• preserve the standard EXE/MSI, bundle offline EXE/MSI from the same compiled program, audit with absolute paths, require four distinct installers, and checksum all four

Verification

• original release run 34221392687 is the failing RED case (359 CRLF formatting reports)
• local Prettier passes and tauri bundle --help confirms the offline bundling command
• this PR's Windows acceptance job verifies the clean Windows checkout before merge
