feat(website): record Claude Code / Fable 5 graph benchmark lane (N=1)

Adds the claude-code-fable agent lane to graph.json: 80 cells (8 repos x
2 prompt families x baseline + 4 graph tools), measured at N=1 because
of Fable 5 pricing and recorded with runs: 1 preserved per the N=1 rule.
All 16 baseline samples were manually inspected (real source reading,
zero web usage, citations spot-verified); all 64 graph-arm samples
completed first-attempt with ttsc-graph and codegraph using MCP in every
cell. The dashboard maps the new lane to Claude Code / Fable 5 and
orders it above Opus.
