Checkpoint tool results before post-execution hook interrupts so resuming a hook never re-runs side-effecting tools. Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com>

Post-execution hooks no longer replay tools when resumed, preventing duplicate side effects in all Hooks v2 sessions.
PostToolUse,PostToolUseFailure, andSubagentStoppreviously interrupted inside the tools node after execution but before its result committed. This moves those interrupts to a checkpoint-safe post-tools boundary while preserving duration reporting and result feedback/context rewriting through private state. Hooks v2 has loaded by default since #5307, so the fix applies regardless ofDEEPAGENTS_CODE_EXPERIMENTAL.Test plan
