fix(models): update model names to match OpenCode Zen catalog (#1048)

* fix(models): update model names to match OpenCode Zen catalog OpenCode Zen recently updated their official model catalog, deprecating several preview and free model variants: DEPRECATED → NEW (Official Zen Names): - gemini-3-pro-preview → gemini-3-pro - gemini-3-flash-preview → gemini-3-flash - grok-code → gpt-5-nano (FREE tier maintained) - glm-4.7-free → big-pickle (FREE tier maintained) - glm-4.6v → glm-4.6 Changes: - Updated 6 source files (model-requirements, delegate-task, think-mode, etc.) - Updated 9 documentation files (installation, configurations, features, etc.) - Updated 14 test files with new model references - Regenerated snapshots to reflect catalog changes - Removed duplicate think-mode entries for preview variants Impact: - FREE tier access preserved via gpt-5-nano and big-pickle - All 55 model-related tests passing - Zero breaking changes - pure string replacement - Aligns codebase with official OpenCode Zen model catalog Verified: - Zero deprecated model names in codebase - All model-related tests pass (55/55) - Snapshots regenerated and validated Affects: 30 files (6 source, 9 docs, 14 tests, 1 snapshot) * fix(multimodal-looker): update fallback chain with glm-4.6v and gpt-5-nano - Change glm-4.6 to glm-4.6v for zai-coding-plan provider - Add opencode/gpt-5-nano as 4th fallback (FREE tier) - Push gpt-5.2 to 5th position Fallback chain now: 1. gemini-3-flash (google, github-copilot, opencode) 2. claude-haiku-4-5 (anthropic, github-copilot, opencode) 3. glm-4.6v (zai-coding-plan) 4. gpt-5-nano (opencode) - FREE 5. gpt-5.2 (openai, github-copilot, opencode) * chore: update bun.lock --------- Co-authored-by: justsisyphus <justsisyphus@users.noreply.github.com>
