3cda73c8b0 simplify MIME detection to text/binary only
Remove magic byte detection in favor of simple UTF-8 validation:
- text/plain for valid UTF-8 content
- application/octet-stream for binary data

Security maintained via headers (X-Content-Type-Options: nosniff, CSP).
Magic signatures preserved as comments for future reference.

Disabled test files:
- test_mime_detection.py.disabled (magic-dependent tests)
- test_polyglot.py.disabled (polyglot format tests)

For full MIME detection, consider using the `filetype` library.

7deba711d4 entropy: exempt small content from check
All checks were successful
CI / test (push) Successful in 38s
Small data has unreliable entropy measurement due to sample size.
MIN_ENTROPY_SIZE (default 256 bytes) sets the threshold.

8addf2d9e8 add entropy enforcement for optional encryption requirement
All checks were successful
CI / test (push) Successful in 38s
Shannon entropy check rejects low-entropy content when MIN_ENTROPY > 0.
Encrypted data ~7.5-8.0 bits/byte, plaintext ~4.0-5.0 bits/byte.
Configurable via FLASKPASTE_MIN_ENTROPY environment variable.

202e927918 add content-hash dedup for abuse prevention
Throttle repeated submissions of identical content using SHA256 hash
tracking. Configurable via FLASKPASTE_DEDUP_WINDOW and FLASKPASTE_DEDUP_MAX.
