Give wayfinder a distinct Deferred section for beyond-destination work

Fog is the undiscovered frontier *toward* the destination — in scope,
just not yet sharp — so it graduates into tickets as the frontier
advances. Work ruled out of *this* effort's scope was being parked in
Fog too, where it read as takeable frontier (an unblocked, unclaimed
ticket is indistinguishable from a live one).

Add a dedicated `## Deferred` section for beyond-the-destination work:
it never graduates (the frontier stops at the destination) and returns
only as a fresh effort if the destination is redrawn. The "Fog or
ticket?" test becomes "Fog, ticket, or deferred?", gated on scope as
well as sharpness, and both charting and working-the-map now defer a
mis-scoped ticket (close it, one line in Deferred) rather than leaving
it on the frontier or logging it in Decisions so far.

Builds on #455 (destination as the leading word / destination fixes
scope).

+Give **`wayfinder`** a distinct **`## Deferred`** section for work that lies _beyond_ the destination, separating it from Fog.

+Fog is the undiscovered frontier _toward_ the destination — in scope, just not yet sharp — so it graduates into tickets as the frontier advances. Work ruled out of _this_ effort's scope was being parked in Fog too, where it read as takeable frontier. It now has its own home: the `## Deferred` section, which never graduates (the frontier stops at the destination) and returns only as a fresh effort if the destination is redrawn. The "Fog or ticket?" test becomes "Fog, ticket, or deferred?" — gated on scope as well as sharpness — and both charting and working-the-map now defer a ticket found beyond the destination (close it, record one line in Deferred) rather than leaving it on the frontier or logging it in Decisions so far.
