feat(v1.5.2.0): Opus 4.7 migration — model overlay, voice, routing

Adapts GStack skill text for Claude Opus 4.7's behavioral changes per Anthropic's migration guide and community findings. Key changes: model-overlays/claude.md: - Fan out explicitly (4.7 spawns fewer subagents by default) - Effort-match the step (avoid overthinking simple tasks at max) - Batch questions in one AskUserQuestion turn - Literal interpretation awareness (deliver full scope) hosts/claude.ts: - coAuthorTrailer updated to Claude Opus 4.7 SKILL.md.tmpl: - Expanded routing triggers with colloquial variants ("wtf", "this doesn't work", "send it", "where was I") — 4.7 won't generalize from sparse trigger patterns like 4.6 did - Added missing routes: /context-save, /context-restore, /cso, /make-pdf - Changed routing fallback from strict "do NOT answer directly" to "when in doubt, invoke the skill" — false positives are cheaper than false negatives on 4.7's literal interpreter generate-voice-directive.ts: - Added concrete good/bad voice example — 4.7 needs shown examples, not just described tone. "auth.ts:47 returns undefined..." vs "I've identified a potential issue..." Regenerated all 38 SKILL.md files. All tests pass.

+**Fan out explicitly.** Opus 4.7 defaults to sequential work and spawns fewer
+subagents than 4.6. When a task has independent sub-problems (investigating multiple
+files, testing multiple endpoints, auditing multiple components), explicitly parallelize:

+**Effort-match the step.** Simple file reads, config checks, command lookups, and

+extended thinking for genuinely hard subproblems: architectural tradeoffs, subtle bugs,
+security implications, design decisions with competing constraints. Over-thinking
+simple steps wastes tokens and time.
+
+**Batch your questions.** If you need to clarify multiple things before proceeding,
+ask all of them in a single AskUserQuestion turn. Do not drip-feed one question per
+turn. Three questions in one message beats three back-and-forth exchanges.

+**Literal interpretation awareness.** Opus 4.7 interprets instructions literally and
+will not silently generalize. When the user says "fix the tests," fix ALL failing tests,

+full scope. If the request is ambiguous, ask once (batched with any other questions),
