fix(cliproxy): use adaptive thinking for Claude Opus 4.7

Browse Source 
Per Anthropic docs, Claude Opus 4.7 only supports adaptive thinking;
manual `thinking.type: "enabled"` with `budget_tokens` is rejected
with HTTP 400.

Switch the claude provider's `claude-opus-4-7` entry from
`type: 'budget'` to `type: 'levels'` with the effort tiers exposed
by the API: `low | medium | high | xhigh`. The proxy is expected to
translate these into `thinking.type: "adaptive"` with the effort
parameter.

Opus 4.6 and Sonnet 4.6 keep `type: 'budget'` for now since the
deprecated mode is still functional on those models.
