agent-start: auto-continue the in-flight turn after account rotation

Previously, when an agent hit a usage limit and rotated to a backup account, claude --resume <id> reloaded the full conversation but sat idle at the prompt — the swapped-in account had all the context yet never answered the pending turn.

The resume marker now supports an optional line 2 (an auto-resume prompt). 5dive-agent-start appends it as the seed positional (claude --resume <id> … continue), staying interactive. The rotation path (telegram plugin 0.4.49) writes "continue" there. Manual /resume still writes a bare id → idle-on-resume, unchanged. The prompt is charset-constrained so a malformed marker can't inject extra argv.

Pairs with telegram plugin 0.4.49.
