CodExorcism+ Release v1.1.0

Test Harness Simplification added beginnings of semantic analysis.

• Rebuilt tests/test_all.sh to derive its file list directly from data/, drive glob/batch runs with a single command, and rely on -t for in-place scenarios.
• STDIN/STDOUT scenario now skips binary fixtures to avoid Python's UTF-8 decoding errors, while every other scenario still exercises them.
• Normalized diffs and wc comparisons are produced per scenario without duplicating helper logic.
• Updated README, docs/cleanup-text.md, and docs/test-suite.md with the new run commands, behavior notes, cleanup instructions, and the preview --metrics documentation.
• Bumped version to 1.1.0 and documented the experimental semantic metrics (--metrics, --metrics-help).
• Installation is now Pip based.
• Added additional test files with human and AI generated text.
