fix(scoping): context gathering reads the whole carrier, asks only the gaps

[leeovery]

The defect

The quick-fix walk re-asked the what and the why the user gave in discovery — both walks, independently. It asked "what exactly is being changed?" against a carrier that says the support mailbox is retiring and everything should point at the new address.

Two causes, both in gather-context.md:

1. Its guard weighed only the seed and description — blind to the session log's Exploration, the half of the carrier the entry skill reads by name and the half holding the shaped context.
2. Its question block is a static fence — all four questions prescribed verbatim, whatever the carrier holds.

The fix

• Section A reads the Exploration alongside the description, mirroring the entry's own wording for where it lives and for the logless quick-fix that has none.
• The guard weighs the whole carrier — seed, description, and exploration.
• Section B emits only the bullets the carrier leaves open: a question the user has already answered reads as not having listened.

Same family as the investigation fix (#578) — the entry reads the carrier, the process skill dropped half of it — and the same repair.

Provenance and proof

Found by scoping-defines-the-quickfix (#579) on its first run; its step-3 claim — questions go to what the carrier does not answer — is the test for this. Re-run pending reload.

Test plan

• Conventions lint 29/29
• The case re-run is the direct probe
