feat: maximize data completeness across L3/L4/TLS/HTTP layers and add E2E test infra
Add SSL_write uprobe for HTTP response capture, HPACK decoder for HTTP/2
header extraction, and AcceptCache for reliable SSL/TC session correlation.
Populate all ClickHouse fields including tcp_meta_options, ip_meta_total_length,
syn_to_clienthello_ms, client_headers, TLS cipher suites/extensions, and
h2_enable_connect_protocol. Increase BPF capture buffers (HTTP 512B, TLS 1024B).
Add distributed E2E testing infrastructure with multi-VM Vagrant setup.
