feat(presets): migrate all aggregator and Bedrock presets to Claude Opus 4.7

- OpenClaw: replace opus-4-6 with opus-4-7 across 17 aggregator presets
  (id, name, primary, modelCatalog); AWS Bedrock entry rewritten to new
  SKU anthropic.claude-opus-4-7 (drops -v1 and dated suffix per official
  4.7 model card) and pricing corrected to $5/$25/$0.50/$6.25 during the
  SKU swap, aligning with schema.rs source of truth
- OpenCode: same replacement for 13 aggregators plus
  OPENCODE_PRESET_MODEL_VARIANTS entries for @ai-sdk/amazon-bedrock and
  @ai-sdk/anthropic, plus AWS Bedrock provider models map
- OpenRouter / TheRouter / GitHub Copilot in claudeProviderPresets use
  dot-style id; update to anthropic/claude-opus-4.7 (missed by 509d2250)
- omo: switch agent/category recommended to opus-4-7; replace key in
  OMO_BACKGROUND_TASK_PLACEHOLDER priority map
- hermes_config.rs: update doc comments and test fixtures to opus-4-7;
  Hermes ModelPanel placeholder and i18n defaultHint examples follow
- i18n unspecifiedHigh category description bumped to 'Claude Opus 4.7
  max variant' to match omo recommended
- Test fixtures updated: therouter preset assertion and opencode Bedrock
  variant lookup now check for opus-4-7
- Sonnet 4.6 / Haiku 4.5 untouched - no official 4.7 release for them
