entropy: exempt small content from check
Small data has unreliable entropy measurement due to sample size.
MIN_ENTROPY_SIZE (default 256 bytes) sets the threshold.

add entropy enforcement for optional encryption requirement
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.

add proof-of-work spam prevention
Clients must solve a SHA256 hash puzzle before paste creation.
Configurable via FLASKPASTE_POW_DIFFICULTY (0 = disabled, 16 = default).
Challenge tokens expire after FLASKPASTE_POW_TTL seconds (default 300).
