The workspaceContext trait was consulted separately at every assembly
site before loading agent notes / work dir — a convention each caller
had to re-remember, where a forgotten check either leaks the user's
agent-memory into non-copilot prompts or silently omits it for the
copilot, and neither fails loudly. The loaders move out of the legacy
runtime file into agents/workspace-context.ts, and
loadWorkspaceContext() applies the trait gate INSIDE: both engines now
call it (the resolver keeps its loader test-seams by injecting them
through), so a future assembly site structurally cannot skip the gate.
Tests pin the gate: non-workspace agents get nulls even when the
loaders would yield values.
