XY-910 Speed up lane inspect status projection

[yvette-carlisle]

Summary

• avoid building the full operator status snapshot for lane inspect
• project only matching active/recent runs for the requested issue and optional run id
• cover run-id filtering and interrupt metadata in the operator lane inspect API tests

Validation

• cargo make fmt
• cargo test -p decodex operator_lane_inspect_api_returns_lane_identity --all-features -- --test-threads=1
• cargo test -p decodex operator_status_projects_terminal_finalized_run_as_pending_not_active --all-features -- --test-threads=1
• cargo test -p decodex parses_lane_inspect_with_run_id_and_project_config --all-features -- --test-threads=1
• cargo test -p decodex operator_lane_inspect_api --all-features -- --test-threads=1
• cargo build -p decodex --bin decodex
• target/debug/decodex lane --config /Users/x/.codex/decodex/projects/decodex inspect XY-910 --json
• cargo make lint-fix
• cargo make test
