feat(models): add Claude Opus 4.7 Optimized via Martian

[kilo-code-bot]

Summary

• Adds `anthropic/claude-opus-4-7:optimized` as a new Kilo-exclusive model hosted by Martian's gateway
• Reasoning defaults to `high` (first variant in the list); full range of variants is still available (high → xhigh → max → medium → low → none)
• Description surfaces a clear data-training notice so users know this third-party provider may train on their prompts/completions
• Pricing is set at 20% off Anthropic list price: $4 input / $20 output / $0.40 cache-read / $5 cache-write per MTok
• Context window: 200k tokens; max completion: 32k tokens

Verification

• Model appears in the model picker with display name "Claude Opus 4.7 Optimized" and the data-training note in its description
• Default reasoning variant is `high` when the model is first selected (no prior localStorage state)
• Full reasoning variant range is accessible via the variant selector
• Routing goes through `gateway: 'martian'` (same gateway as `grok_code_fast_1_optimized_free_model`)
• Usage billing reflects the discounted rates (not `null` / free)

Visual Changes

N/A — model metadata only, no new UI components.

Reviewer Notes

• `CLAUDE_OPUS_4_7_OPTIMIZED_MODEL_ID` (`anthropic/claude-opus-4-7:optimized`) uses a hyphen in `4-7` (matching Martian's model string) while the existing `CLAUDE_OPUS_CURRENT_MODEL_ID` uses a dot (`anthropic/claude-opus-4.7`); the two are intentionally distinct.
• `getModelVariants` checks for this model's exact `public_id` before the generic `isOpusModel && includes('4.7')` branch, so the custom variant ordering (high-first) is applied only to this optimized variant.
• List prices sourced from Anthropic pricing page: $5 input / $25 output / $6.25 cache-write / $0.50 cache-read per MTok. 20% discount applied uniformly.

Code Review Summary

Status: No New Issues | Recommendation: Awaiting resolution of existing thread

Executive Summary

The incremental commit (90d166e) changes only one line: the model description now reads "a stealth inference partner" instead of a Martian hyperlink. No bugs, logic errors, or security issues in the new code.

Incremental Change

Commit 90d166e — Change provider to stealth:

• apps/web/src/lib/ai-gateway/providers/anthropic.constants.ts line 35: replaced [Martian](https://withmartian.com) with a stealth inference partner in the user-facing description string.
• gateway: 'martian' (line 40) remains unchanged — this is internal routing and is intentionally not reflected in the description.

Open Thread

The existing inline comment from @lambertjosh at line 11 — asking whether this constant belongs in anthropic.constants.ts vs. a Martian-specific file — is still unresolved. The description change does not address the file-organization concern raised there.
