fix(amazon-bedrock): correct Meta, Mistral, and Writer catalog

[rekram1-node]

Summary

Meta/Mistral/Writer split of #6637, based on current dev.

• Audit all 25 existing entries; preserve every existing ID and route.
• Add complete shared lab metadata for Magistral, Ministral 3, and Voxtral models.
• Correct Writer X4/X5 native metadata while keeping Bedrock host limits as provider overrides.
• Correct Llama 3.3/4 and Mistral dates, modalities, capabilities, and confirmed host limits.
• Correct Voxtral Small pricing.

Live checks confirmed Llama 4’s 8,192 output limit, Bedrock Scout’s AWS-documented 10M context, and Ministral 8B/14B image input. Proposed Llama 3.2 additions were excluded after AWS returned explicit end-of-life errors.

Sources are in leading TOML comments, including AWS cards and first-party model configs.

Validation

• bun validate
• All new lab entries contain required capabilities, modalities, context, and output
• git diff --check
• No model deletions or route changes

Action items

• [high] [possible mistake] providers/amazon-bedrock/models/writer.palmyra-x4-v1:0.toml:11 - Check: Bedrock host limits must remain real overrides of the shared lab window (limit.context / limit.output), not a renamed field. Why: Lab writer/palmyra-x4 now uses context = 128_000. The Bedrock files replace the previous host context = 122_880 with input = 122_880 only, so deep-merge publishes limit.context = 128_000 for writer.palmyra-x4-v1:0 and us.writer.palmyra-x4-v1:0 instead of the prior Bedrock window. That contradicts the PR goal of keeping Bedrock host limits and diverges from the X5 pattern, which still overrides context. Action: If Bedrock’s window is still 122,880, set [limit] context = 122_880 (and output = 8_192) on both X4 routes; use limit.input only if AWS documents a distinct max-input cap in addition to context. Align us.writer.palmyra-x4-v1:0.toml the same way.

Fixed in f91f6c1. Both Palmyra X4 provider entries now preserve Bedrock’s limit.context = 122_880 and limit.output = 8_192; the erroneous limit.input replacement is removed. bun validate and git diff --check pass.

Follow-up from metadata review: Palmyra X4 keeps the corrected release_date = 2024-10-09, but last_updated is restored to its existing later value 2025-04-28. Release and last update are distinct facts. bun validate passes.
