feat(blocks): surface deprecated block and model warnings on canvas

[TheodoreSpeaks]

Summary

• Add a deprecated?: { replacedBy? } field to BlockConfig and annotate 37 legacy block configs with their successors
• Render an amber "deprecated" badge on canvas blocks when the block type or its selected model is deprecated; clicking opens Chat with a block-scoped prompt to upgrade it (gated on edit permission, hidden in diff mode)
• Add isModelDeprecated / getModelReplacement model accessors; only badge when a concrete upgrade target exists (drops vision, which has no successor)
• Fix the workflow-panel mothership-send-message listener to forward contexts + preventDefault (also repairs existing terminal/logs "Fix in Chat")
• Clear inherited deprecated on 20 successor blocks built by spreading their deprecated predecessor (they were self-referencing)
• Add a check-block-registry invariant that every replacedBy resolves to a real, GA, non-deprecated block

Type of Change

• New feature

Testing

Tested manually against local workflows with deprecated blocks/models. bun run lint:check, check:api-validation:strict, check-block-registry, and providers/models.test.ts all pass.

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing

PR Summary

Low Risk
Mostly UI and declarative block metadata; execution paths are unchanged and the copilot listener fix is a small behavioral improvement with limited blast radius.

Overview
Introduces deprecated.replacedBy on BlockConfig and tags many legacy integration/trigger blocks so existing canvas instances can show an amber deprecated badge (hidden in diff mode).

Workflow canvas:getBlockDeprecation drives the badge for superseded block types or deprecated catalog models; editors can click to open Chat with a block-scoped upgrade prompt (sendMothershipMessage + workflow_block context), with PostHog deprecated_block_fix_clicked. WorkflowBlockView renders the badge and gates fixes on edit permission.

Panel: The mothership-send-message handler now preventDefaults, switches to the copilot tab, and forwards contexts into copilotSendMessage (fixes block-scoped “Fix in Chat” flows).

Models: Adds isModelDeprecated from the static provider catalog and tests.

Tooling:check-block-registry validates every replacedBy points at a real, non-deprecated, non-preview successor; v2 blocks clear inherited deprecated from spread parents.

• Adds static model-deprecation lookup helpers and tests.
• Validates block replacement targets in the registry check.

Confidence Score: 5/5

This looks safe to merge.

• The actionable badge now supports focus and Enter or Space activation.
• Read-only badges remain non-interactive.
