Colby McHenry bfcd873993 feat(mcp): steer flow questions to codegraph_trace first (tightens variance) ...

codegraph_trace was absent from every steering intent map — all three guidance
files routed "how does X reach Y" to context+explore, never to the trace tool.
So agents used trace only by chance; when one didn't, it floundered
reconstructing the path with search+callers (an 18-call run vs ~6 for trace-users).

Add codegraph_trace to the intent map + a "flow" common chain (trace from->to
FIRST = the whole path in one call, then ONE explore for bodies) across all three
synced files (server-instructions, instructions-template, .cursor rule).

Validated on excalidraw (hard "to the screen" Q, n=4 before/after):
- call count 3-10 -> 3-4 (over-drill outlier gone)
- duration 64-112s -> 51-74s
- trace adoption 3/4 -> 4/4; search+callers path-reconstruction -> 0
- fully-clean runs (0 Read, 0 Grep) 0/4 -> 2/4; best 3 cg / 0 / 0 / 51s
