fix: P1 correctness and operational fixes from FAR-104/FAR-105 analysis

5. Cap log stream reconnect attempts at 50 — prevents infinite
   reconnect loops during sustained API partitions.

6. Fire keepalive refresh earlier — tick 1 + every 12 ticks (~3min)
   instead of every 16 ticks (~4min), providing better safety margin
   under the 5-minute reaper window.

7. Catch rejections from onLog inside keepalive — add .catch(() => {})
   to prevent unhandledRejection on SSE backpressure.

8. Prevent sanitized-name collisions — extend slugs to 16 chars each,
   add a 6-char SHA-256 hash suffix, shorten prefix to `ac-` to stay
   well within the 63-char DNS label limit.

10. Fix config-hint parity for nodeSelector and labels — parse both
    `key=value` multiline text and JSON objects, matching what the
    textarea hint promises.

11. Large-prompt fallback via Secret — prompts >256 KiB are staged as a
    K8s Secret and mounted as a volume instead of passed via env var,
    protecting against the ~1 MiB PodSpec limit.

13. Track last-seen log timestamp on reconnect — anchor sinceSeconds at
    the last received log line instead of stream start, fixing FAR-105
    duplicative logs. Belt-and-braces: dedupe assistantTexts at the
    parser boundary in parse.ts.
