Upgrade smithers-orchestrator to smthrs

[roninjin10]

What

The smithers-orchestrator package was renamed on npm to smthrs (and the @smithers-orchestrator/* scope to @smthrs/*), with no compatibility alias published under the old name. This PR migrates svvy from smithers-orchestrator@0.28.0 to smthrs@0.33.0.

Changes

• Renamed all smithers-orchestrator / @smithers-orchestrator/* references to smthrs / @smthrs/* across the repository (imports, package manifests, docs, workflow definitions).
• Updated dependency ranges to ^0.33.0 (e.g. smthrs and @smthrs/agents in workflows/package.json).
• Regenerated lockfiles; they resolve the published smthrs/@smthrs/* 0.33.0 packages with integrity hashes. Regeneration emitted only peer/platform warnings.

Verification

• git grep smithers-orchestrator is clean (zero matches).
• The rename and version match the Smithers 0.33.0 changelog; smthrs and @smthrs/agents 0.33.0 are published on npm.
• Reviewer note from the upgrade pipeline: "Mergeable. The required grep is empty; the 0.33.0 package and scope rename matches the Smithers changelog; smthrs and @smthrs/agents 0.33.0 are published; JSON and diff checks pass; regenerated lockfiles are clean and consistent."
