The cascade tracer's JSON response now carries:
- Top-level `cascade_mode` (string): the active mode (delegated /
strict). Helps reviewers correlate the visible_start with the mode.
- Top-level `chain.visible_start` (int): chain.VisibleStart(leaf, mode)
— the lowest level whose grants the leaf can see, accounting for any
inherit:false fence in delegated mode (always 0 in strict mode).
- Per-level `inherit` (*bool, omitempty): the level's explicit inherit
value, nil when absent. A reviewer can scan the levels and see which
one fences ancestors.
The level's `exists` flag now also fires for `permissions:` and
`inherit:` entries (previously it only checked Allow/Deny/Admins),
so the response correctly reflects modern .zddc files that use the
permissions map.
Test: TestServeProfileEffectivePolicy_InheritFence builds a vendor-
folder layout, asks the tracer about a my-company user, confirms
decision=false, visible_start=1 (fence at /Vendor/), leaf.Inherit=
&false, root.Inherit=nil.
