fix(cliproxy): address Presto review feedback on Opus 4.7

- model-catalog: change `claude-opus-4-7` description from "Latest
  flagship without thinking" to "Latest flagship model". The model
  supports thinking budget (min 1024, max 128000) but doesn't enable
  it by default; the old wording implied no thinking support, which
  was misleading. Aligns with the `claude` provider's description.

- generator: add DEFAULT_ANTIGRAVITY_ALIASES entry for non-thinking
  `claude-opus-4-7`, restoring symmetry with `claude-sonnet-4-6`
  (which has both -thinking and non-thinking aliases). Bump
  CLIPROXY_CONFIG_VERSION 18 → 19 to trigger regeneration on upgrade.

Addresses PResto atrvd/ccs#8 issues #2 (important) and #3 (suggestion).
