itd-10 lists a lifeboat among the .abcd/ contents destroy deletes; disembark always writes the lifeboat out-of-tree

A premise contradiction (severity minor) found by the cross-document consistency pass.

• End A: .abcd/development/intents/drafts/itd-10-purge-uninstall.md:16 — "AND the entire .abcd/ namespace (including lifeboat, dev artefacts, logbook, and config)"
• End B: .abcd/development/brief/04-surfaces/02-disembark.md:198 — "The lifeboat is written out-of-tree, so the source repo has nothing to gitignore."

itd-10's destroy promises to delete the .abcd/ namespace 'including lifeboat'. The disembark chapter writes every lifeboat to an operator-chosen destination outside the source repository, so the source has nothing to gitignore. That leaves no lifeboat under .abcd/ for destroy to remove, and the draft's list of what it deletes names an artefact the surface never puts there.
