Commit Message

tls: measurement gate — steady state ≈ plaintext; heap sized from data

Band procedure (3 alternating runs each, R=20k c=64, nginx origin):
TLS matches plaintext on throughput (~19.92k both) and p50 (139-148µs
vs 153-157µs); p99 within ~100µs. The TLS p99.9 band sat at a constant
~32.5ms vs ~5.5ms plaintext — a 30s run shrank it to 13.3ms and moved
the mass to p99.99, proving it is the startup handshake burst under
coordinated-omission correction, not a steady-state stall. Amortized
by connection lifetime; session resumption would shrink the burst.

Heap, measured via the new gauges: ~161 KiB per live TLS connection
(consistent at c=64 and c=256: 11.1 and 42.2 MiB carved), 0.9 MiB
process baseline, zero rejections everywhere. The guessed 64 MiB
constant is replaced by a startup derivation — tls_heap_base_bytes +
tls_heap_per_connection_bytes * connections_max * workers — so every
connection slot on every worker can be TLS (392 MiB on an 8-core box,
virtual: pages touch as connections carve; idle RSS ~21 MB, verified).
