Update claude-api skill: Claude Opus 5 (#1476)

Browse Source 
* Update claude-api skill: Claude Opus 5

- Add Claude Opus 5 (`claude-opus-5`) as the default model across all
  SDK examples, model tables, pricing, and migration guidance.
- Add an Opus 5 migration section covering the API changes that come
  with it, and move Opus 4.8 into the previous-generation slot.
- Drop the Opus 4.7 fast-mode guidance, which no longer applies.
- Scope the server-side fallbacks beta header to the current version.

* Update claude-api skill: Opus 5 fast-follow corrections

- Server-side refusal fallbacks are available on Claude Platform on AWS,
  not just the Claude API. Correct the availability statements in
  SKILL.md, the migration guide, and the platform-availability table.
- Simplify the effort guidance: start at `high` (the API default) and
  sweep down, rather than starting at `xhigh` for coding work.
- Add a time-to-first-token section with the prompt instruction that
  reduces pre-answer thinking on latency-sensitive routes.
- Replace the two separate thinking-disabled mitigations with the single
  combined instruction that covers both failure modes.

> **Claude Opus 5:** thinking is on by default — omitting `thinking:` runs adaptive (`['type' => 'adaptive']` is equivalent), unlike Opus 4.8/4.7 where omitting it meant no thinking. `['type' => 'disabled']` is accepted only at effort `high` or lower; pairing it with `xhigh`/`max` returns a 400.
> **Older models:** Use `thinking: ['type' => 'enabled', 'budgetTokens' => N]` (budget must be < `maxTokens`, min 1024).
`$block->type === 'thinking'` also works for the check; `instanceof` narrows for PHPStan.
