add handoff-8: round 5/6 summary + ADR-0024 execution handoff
Round 5 + 6 testing + i18n sweep + thiserror migration +
ADR-0023 (direction) + ADR-0024 (accepted execution plan).
Frames the next session's primary task: execute ADR-0024
Phases A-F non-interactively. Spells out escalation criteria
("ADR doesn't cover this" not "I'm unsure which choice is
better"), per-phase commit checkpoints as the user
touchpoint, and the autonomous-by-default disposition the
user has explicitly requested.
Smoke test refreshed (empty hint wording, value-literal slot
hint, q removed, catalog-driven CLI error). Sharp-edges
section covers the design's traps (scannerless walker,
schema-aware parse, WalkContext writes, DynamicSubgrammar
expansion, Optional continuations closing the round-5 'save
Tab can't offer as' gap, IdentSource::Types replacing the
TYPE_SLOT_LABEL magic string, path-bearing UX change
requiring quoting for paths-with-spaces, hand-curated help
text staying out of grammar-derivation scope).
