Adds pytest coverage for flock_tap.py's parsing, classification, and
byte/FRP/cloud-IP accounting, plus a .gitignore for Python caches and
capture/scan output artifacts.
The packet-level tests double as regression guards for the recently fixed
detection bugs (FRP auth-payload firing on data segments not just SYN,
no bytes_up inflation, and known-Flock-IP correlation); they fail against
the pre-fix code and pass after it. scapy-dependent tests skip cleanly when
scapy is unavailable.

- Move the FRP auth-payload scan out of the SYN-only branch. SYN packets carry
no payload, so payload-based FRP detection never fired; it now runs on every
TCP segment where the frp/auth/proxy_type bytes actually appear.
- Remove the per-packet `bytes_up += 64` approximation in on_tcp_connect, which
double-counted against real ip.len accounting and corrupted bandwidth stats.
- Correlate connections against known Flock cloud IPs (static seed list + IPs
learned from DNS answers) so cameras that reach cloud IPs without their own
DNS/SNI are classified CLOUD_CONNECTED.
- Match the Flock auth0 tenant in DNS detection, consistent with the SNI path.
- Install a SIGINT handler so the report is always produced on Ctrl+C.
- Drop unused scapy TLS imports (SNI is parsed manually).
