Rebased onto origin/main (5bf78671f4).
Conflict resolved in crates/buzz-agent/src/config.rs: kept our generated
anthropic_thinking_config_generated as the sole authority; absorbed main's
thinking shapes, ThinkingSummary enum + parse_thinking_summary, and the
thinking_summary field in Config wired through from_env / for_discovery.
Fixed CI job (model-capabilities): actions/checkout comment v6 → v6.0.3,
Swatinem/rust-cache SHA bumped to tagged v2.9.1 (c1937114) to resolve
zizmor ref-version-mismatch finding (r3730151005).
