docs: fix corrupted README

[raphgm]

The README had a UTF-16-encoded blob (a contributor's Git Flow log) accidentally appended after the footer, introducing NUL bytes and garbled text.

Changes:

• Removed the corrupted UTF-16 appended content (NUL-byte garbage).
• Normalized line endings from CRLF to LF.
• Fixed a missing space after a period and a double space in the Acknowledgements section.
• Moved the Acknowledgements section above the closing footer so the footer reads last.
