Commit Message

sim: h2c client fault menu (full parity, 2/2)

Rounds out the h2c simulator to match the H1 fault menu. The multiplexed
h2c client now draws a per-stream request kind — GET, small POST, a
~10 KiB POST, or a deliberately-malformed request (missing :scheme, a
stream error the proxy answers with RST_STREAM PROTOCOL_ERROR) — and
sometimes vanishes after the first response byte (the H2 twin of H1's
abort_mid_response, exercising multi-stream teardown when the client
drops mid-multiplex).

The ~10 KiB body sits above the 8 KiB half-window and below the 16 KiB
advertised stream window, so it drives the proxy's request-body
flow-control release (WINDOW_UPDATE emitted only after the upstream
write, the §1.4 rule) without needing a window-accounting test client.
The virtual origin's buffer grew to 32 KiB to accept it.

Sweep: seeds 0..1500 clean, 19528 responses across both proxies. Docs
updated (sim module doc, DESIGN.md, CLAUDE.md); the >window flow-control
stall (needs a window-accounting client) is recorded as the remaining
sim gap. Bodies beyond the window stay covered by the unit + integration
send_data pacing tests.
