Adds claude-fable-5 and claude-opus-5 as selectable models in the web UI dropdown and CLI, with pricing entries for --show-cost. Also swaps the retired claude-sonnet-4-20250514 default (returns 404 as of its June 2026 retirement) for claude-sonnet-5 across run_pipeline.py, generate_report.py, index.html, README, and CLAUDE.md.

Newer Claude models (Opus 4.6+, Sonnet 4.6+, Fable/Mythos 5) reject the temperature request param outright (400 error) in favor of adaptive thinking + effort. Added supports_temperature() in llm_client/client.py and wired it into every Anthropic call site (AuditClient, PipelineClient, and the report-generator's LLM dedup call) so temperature is only sent to models that still accept it.

Should the default say claude-sonnet-5?

Brings client.py's defaults in line with the claude-sonnet-4-20250514 ->
claude-sonnet-5 swap already made in run_pipeline.py, generate_report.py,
index.html, README, and CLAUDE.md.
