Audit logging:
- audit_log table with event tracking
- app/audit.py module with log_event(), query_audit_log()
- GET /audit endpoint (admin only)
- configurable retention and cleanup

Prometheus metrics:
- app/metrics.py with custom counters
- paste create/access/delete, rate limit, PoW, dedup metrics
- instrumentation in API routes

CLI clipboard integration:
- fpaste create -C/--clipboard (read from clipboard)
- fpaste create --copy-url (copy result URL)

5849c7406f add /register endpoint for public certificate registration
Public endpoint allows anyone to obtain a client certificate for
authentication. Features:

- Higher PoW difficulty than paste creation (24 vs 20 bits)
- Auto-generates CA on first registration if not present
- Returns PKCS#12 bundle with cert, key, and CA
- Configurable via FLASKPASTE_REGISTER_POW

Endpoints:
- GET /register/challenge - Get registration PoW challenge
- POST /register - Register and receive PKCS#12 bundle

45712ea93f add anti-flood: dynamic PoW difficulty under load
When paste creation rate exceeds threshold, PoW difficulty
increases to slow down attackers. Decays back to base when
abuse stops.

Config:
- ANTIFLOOD_THRESHOLD: requests/window before increase (30)
- ANTIFLOOD_STEP: difficulty bits per step (2)
- ANTIFLOOD_MAX: maximum difficulty cap (28)
- ANTIFLOOD_DECAY: seconds before reducing (30)

bfc238b5cf add CLI enhancements and scheduled cleanup
CLI commands:
- list: show user's pastes with pagination
- search: filter by type (glob), after/before timestamps
- update: modify content, password, or extend expiry
- export: save pastes to directory with optional decryption

API changes:
- PUT /<id>: update paste content and metadata
- GET /pastes: add type, after, before query params

Scheduled tasks:
- Thread-safe cleanup with per-task intervals
- Activate cleanup_expired_hashes (15min)
- Activate cleanup_rate_limits (5min)

Tests: 205 passing

7deba711d4 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.

8addf2d9e8 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.
