Make Claude 4.x routing version-aware; add Opus 4.8 (v1.7.0)

Opus 4.8 is now the default Claude model, but the skill was pinned to a
4.7-only worldview and asserted stale, version-specific facts as hard rules.

- Restructure Claude LLM routing into version-aware blocks: durable advice
  generalized across 4.6/4.7/4.8, new Opus 4.8 (current default) profile,
  Opus 4.7 kept and clearly labeled.
- De-hardcode the Claude Code "xhigh effort" note. Effort/thinking depth is
  harness-managed on current Opus models; the prior claim was 4.7-specific
  and unverifiable for 4.8, so it's generalized rather than replaced with a
  fabricated 4.8 number.
- Template M renamed "Opus 4.7 / 4.8 Task Brief" (heading, TOC, body).
- Pattern 36 covers 4.7 and 4.8.
- Fix stray "schema" |" fragment dangling off the pattern 37 row in
  patterns.md.
- Bump version 1.6.0 -> 1.7.0 and add README history entry.

 ## ℹ️ Version History
 
+- **1.7.0** — Opus 4.8 compatibility. Made Claude 4.x routing version-aware: durable advice generalized across 4.6/4.7/4.8, added Opus 4.8 (current default) profile, kept Opus 4.7 labeled. De-hardcoded the effort-level note (now harness-managed). Template M and pattern 36 cover 4.7 and 4.8. Fixed a stray fragment in patterns.md.
 - **1.6.0** — Opus 4.7 update. Added Template M (Opus 4.7 Task Brief). Updated Claude and Claude Code routing for literalism, adaptive thinking, xhigh effort, and session hygiene. Added patterns 36–37.
 - **1.5.0** — Added more tool routing. New Agentic AI and 3D Model AI routing added. Fixed description to 189 chars. Removed token estimate from output. Added instruction layer and copywriting placeholders
 - **1.4.0** — Added reference image editing detection, ComfyUI support, Prompt Decompiler mode. Fixed trigger description to invoke correctly in Claude Code. 3 new templates added to references folder

-- Be explicit and specific — Claude 4.x follows instructions literally. Opus 4.7 especially: it does exactly what you say, nothing more. Missing context = narrow literal output, not a smart guess.

+- Be explicit and specific — Claude 4.x follows instructions literally. It does exactly what you say, nothing more. Missing context = narrow literal output, not a smart guess.

+- XML tags help for complex multi-section prompts: `<context>`, `<task>`, `<constraints>`, `<output_format>`
 - Provide context and reasoning WHY, not just WHAT — Claude generalizes better from explanations
 - Always specify output format and length explicitly
-- For complex or multi-step tasks on Opus 4.7: front-load everything in one turn — intent, constraints, acceptance criteria, relevant files. Every extra back-and-forth turn adds reasoning overhead and token cost.
-- Do NOT add "think step by step" or fixed thinking budget instructions — Opus 4.7 uses adaptive thinking and calibrates depth automatically. To influence depth: "Think carefully before responding" (more) or "Prioritize responding quickly" (less).
-- Use Template M for agentic or multi-step tasks on Opus 4.7.

+*Opus 4.8 (current default):*
+- Shares 4.7's literalism and adaptive thinking — the same front-loading discipline applies. Treat the first turn as the only turn for complex work: intent, scope, constraints, acceptance criteria up front.
+- 1M-token context window — large multi-file context can go in a single prompt, but keep it relevant; padding still dilutes attention.
+- Effort/thinking depth is calibrated automatically — do not specify an effort level or thinking budget.
+
+*Opus 4.7 (still selectable):*
+- More literal than 4.6 — vague first turns produce narrower results. Front-load intent, file scope, constraints, and acceptance criteria.
