feat(claude): upgrade effort toggle from "high" to "max"

Per Anthropic's effort parameter docs, "high" is the API default and
setting effortLevel="high" is equivalent to omitting the field entirely.
The toggle previously produced no effect.

Claude Opus 4.6, Sonnet 4.6, and Opus 4.7 now support a "max" level
that enables unconstrained reasoning. Rename the checkbox (effortHigh
-> effortMax) and write effortLevel="max" when toggled on. Existing
"high" values in user configs are left untouched.

Updates zh/en/ja locales and user-manual entries accordingly.
