chore: normalize all tracked files to LF line endings

Mechanical application of the `.gitattributes` rules from the prior commit.
All 50 files differ only in line endings — verified by
`git diff --cached --ignore-all-space` being empty.

Before: main had 42 CRLF + 27 LF Python files plus mixed-ending in YAML,
templates, and shell scripts. After: every text file is LF (except the
Windows-native *.ps1, *.bat scripts which remain CRLF per gitattributes).

This eliminates the noisy-diff failure mode seen in PR #102, where a
small logic change produced a 918-line diff due to whole-file CRLF→LF
conversion.
