Add reliable Effect Machine planning lint rules

[SandroMaglione]

Summary

• add recommended rules for conflicting invocation identities, browser APIs during planning, and nondeterministic planning
• strengthen async-planning detection and safe redundant-resolver fixes
• document direct refactors in every diagnostic and the package guide, with conservative scope and shadowing guards

Changeset

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

Validation

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

Local smoke checks also passed for pnpm perf:types, pnpm perf:runtime, and installation of the packed Oxlint plugin with its diagnostic and fixer.
