ci: clear the snapshots-and-artifacts lane — lint sweep and TUI snapshot re-record

Lint: eslint --fix over the merge-crossed projection/command files (arrow
parens, trailing commas, unnecessary assertions), Extract<> replaces the
keyof-map & string intersections no-redundant-type-constituents rejects,
the fold-adapter's merge loop drops its non-null assertions for a
bounds-carrying cursor, one JSDoc line wrapped under max-len (api-catalog
regenerated). Snapshots: the four TUI goldens re-recorded for the merged
event-count shift (the durable command lifecycle adds one event to the
seeded diagnostics log). The headless advanced-toolchain snapshot passes
on CI and fails locally in this sandbox both with and without these
changes (30s child timeout — environment-bound, tracked in the ledger).
