Add Effect Machine Oxlint review tooling

[SandroMaglione]

Summary

• add @typeonce/oxlint-plugin-effect-machine with no-redundant-resolve, no-async-planning-callback, and prefer-inline-handle
• document the post-implementation machine review boundaries and ship focused rule plus packed-consumer coverage
• keep core, devtools, and the Oxlint plugin in one synchronized Changesets fixed group

Changeset

• Added or updated for a library or package-metadata change
• Not required because this PR does not change a publishable package

The minor changeset adds the plugin and schedules all three fixed packages for the same version.

Validation

• pnpm check
• Automated type-performance measurement passed or was not required
• Automated runtime- and memory-performance measurement passed or was not required

Local pnpm perf:types and pnpm perf:runtime smoke tests passed. CI classified the core type and runtime performance surfaces as unaffected, so both measurement jobs were correctly skipped and their aggregate gates passed.
