perf(tui): prewarm runtime plugins before first send#90782

Codex review: needs maintainer review before merge. Reviewed June 9, 2026, 4:19 AM ET / 08:19 UTC. Summary PR surface: Source +32, Tests +49. Total +81 across 3 files. Reproducibility: yes. for the code path, but not as a freshly rerun performance profile: current main lacks embedded history prewarm and the PR body provides before/after profile data. This read-only review did not rerun the local TUI profiling, and the current head changed after the profile evidence. Review metrics: 1 noteworthy metric.
Merge readiness Overall follows the weaker of proof and patch quality, so missing proof can cap an otherwise strong patch. Rank-up moves:

Security Review detailsBest possible solution: Land only after final-head local TUI proof confirms the moved cold load is worth the slower history/startup path; otherwise use a cancellable post-ready warmup that preserves fast readiness. Do we have a high-confidence way to reproduce the issue? Yes for the code path, but not as a freshly rerun performance profile: current main lacks embedded history prewarm and the PR body provides before/after profile data. This read-only review did not rerun the local TUI profiling, and the current head changed after the profile evidence. Is this the best way to solve the issue? Acceptable but still a maintainer tradeoff: warming during embedded history is a narrow implementation that preserves the public backend contract, but it deliberately shifts latency into startup/history readiness. A cancellable post-ready warmup is the safer alternative if fast startup is the priority. AGENTS.md: found and applied where relevant.

Shiny media proof means a screenshot, video, or linked artifact directly shows the changed behavior. Runtime, network, CSP, and security claims still need visible diagnostics. How this review workflow works

This patch moves the measured

EmbeddedTuiBackend.loadHistory()using the same resolved agent workspace as the local send path.prewarmAgentRuntimehook, no public harness prewarm API, and no separatewarming runtimesubmit state.Relationship to #86981
#86981 prewarms the selected plugin harness runtime and was stacked on the closed #86930 base hook. In this repro the selected harness is the built-in OpenClaw runtime, so that approach does not remove the measured
ensureRuntimePluginsLoadedspike. This PR targets the measured local embedded TUI stage directly without adding another hook seam.Verification
