Summary

This PR sets up continuous performance measurement with CodSpeed for OpenAlice.

It adds a vitest-based benchmark harness using the official @codspeed/vitest-plugin, an initial set of benchmarks covering hot-path pure functions, and a GitHub Actions workflow that runs the benchmarks on every push and pull request.

Changes

• Added @codspeed/vitest-plugin as a dev dependency.
• Added vitest.bench.config.ts, a dedicated benchmark config that loads the CodSpeed plugin and mirrors the workspace path aliases from vitest.config.ts (so benchmarks can import from src/* and the workspace packages without a prior dist/ build).
• Added benchmarks/core.bench.ts with benchmarks for CPU-bound, deterministic helpers:
  • parseDuration (scheduling / cron / pump timers)
  • compareVersions and getRepoSlug (version awareness)
  • inferCredentialVendor and resolveAnthropicAuthMode (credential inference)
• Added a bench script to package.json.
• Added .github/workflows/codspeed.yml, mirroring the existing CI's pnpm + Node 22 setup. It uses OIDC authentication and runs in CodSpeed's simulation instrument.
• Added the CodSpeed badge to the README.

Verification

The benchmarks were run locally with the CodSpeed CLI in simulation mode and uploaded successfully, linked to the 2233admin/OpenAlice repository. All four benchmarks execute and report results.

Next steps

• Once merged, CodSpeed will track performance on every PR and flag regressions.
• Expand coverage by adding benchmarks for additional hot paths (e.g. entity store, event log, compaction) as they evolve.
• You can run the suite locally with pnpm bench.
