bvandeusenandClaude Opus 5.5 a805e1d539 fix(host_agent): every Docker read is bounded, and the agent reports its own footprint (#5764) ...

#5764 "The agent reads a container's whole log backlog into memory, on its
main loop, with no overall deadline". Docker03's 1.13.0 agent went silent
for a day at 2.1 GB and 46 h of CPU, then ignored SIGTERM.

- One shared reader, _docker_get: each answer has an overall deadline and a
  byte cap, not only a per-recv timeout. A trickling or endless body is cut
  off (15 s / 32 MiB for JSON, 5 s / 4 MiB for a log read).
- Container logs: since the cursor but only the newest 2,000 lines, all
  within 10 s. A note says when older lines were skipped, and a container
  whose answer is too big skips ahead to now instead of re-reading its
  backlog every interval.
- The agent reports its own RSS and CPU; Steward records agent_rss_bytes
  and agent_cpu_pct, so a runaway agent shows before it goes silent.

Agent 1.15.0.
