feat(models): sunset tiers for models mirroring blocks (legacy amber / deprecated red)

[TheodoreSpeaks]

Summary

Follow-up to the block sunset tiers (#5793). Gives models the same two-tier lifecycle.

• Adds ModelDefinition.sunset: { status: 'legacy' | 'deprecated' } — identical shape to BlockConfig.sunset; replaces the old deprecated: boolean.
• Classifies the 52 sunset catalog models: 33 deprecated (red — provider has retired them, API calls fail) and 19 legacy (amber — superseded but still callable). The 33 were verified against each provider's live retirement docs (xAI grok-3/4 gen, Bedrock llama-3.x, Anthropic 4-0/sonnet-4-0/3-haiku, Google/Vertex gemini-2.0, Groq, Mistral, Cerebras, DeepSeek).
• Retired (deprecated) models are hidden from the model picker (getModelOptions) but stay isKnownModelId, so existing pinned workflows still validate.
• Canvas badge: retired model → red "deprecated"; legacy model → amber "legacy" (same tiers as blocks).
• Removes 2 phantom Bedrock catalog ids that never shipped on Bedrock (amazon.nova-2-pro-v1:0, mistral.mistral-large-2411-v1:0).

Type of Change

• New feature

Testing

PR Summary

Medium Risk
Touches the central model catalog and all model pickers/agents; mis-tagged sunset status could hide callable models or leave failing models visible, though pinned workflows are intentionally preserved.

Overview
Replaces the flat deprecated: boolean on catalog models with sunset: { status: 'legacy' | 'deprecated' }, aligned with block sunset semantics. Catalog entries are reclassified (superseded-but-callable vs provider-retired), and two phantom Bedrock IDs are removed from the catalog.

User-facing behavior: deprecated models are dropped from getModelOptions, copilot static model lists, and VFS model menus, but remain known IDs so existing workflows still validate. legacy models stay in pickers. On the canvas, workflow blocks now show red “deprecated” vs amber “legacy” model badges with tier-specific tooltips and mothership fix prompts (via getModelSunsetStatus). The public models catalog marks sunset models with deprecated: !!model.sunset.

API: getModelSunsetStatus is the source of truth; isModelDeprecated now means “any sunset tier.” Bedrock geo-profile unsupported list is updated after removing a retired Mistral catalog entry.

Greptile Summary

This PR adds two-tier lifecycle handling for sunset models. The main changes are:

• Replaces the model deprecated flag with legacy and deprecated sunset statuses.
• Keeps legacy models selectable while hiding retired models from user and Copilot menus.
• Adds distinct amber and red canvas badges for legacy and retired models.
• Removes two Bedrock catalog IDs that were never available from that provider.

Confidence Score: 5/5

This looks safe to merge.

• The Copilot fallback now excludes retired models consistently with the picker and VFS menu.
• Legacy models remain available in execution and editor paths.
• No blocking issues remain in the changed code.
