After each state-mutating dispatch, evaluate world.endings in priority
order (true > wrong > bad). The first whose whenFlags are all satisfied
sets state.endedWith and appends a kind:'ending' transcript line. Once
ended, further dispatches return a "story has ended" narration.
Also update test-world fixtures and placeholder ending markdown files
to use whenFlags: { _never: true } instead of {} so that vacuously-true
empty flags don't accidentally fire on every successful turn.

Verifies blocked movement, key-permitted passage, and that the key is
not consumed by passing through.

light X with Y validates the named instrument and reuses handleLight.
use X / use X on Y route through the encounter dispatcher; if no encounter
consumes it, the dispatcher narrates the fallback. The encounter matcher
also rejects transitions whose required item doesn't match the typed
instrument, so a mistyped instrument fails cleanly.

\`light X\` finds a lighter (item with lighter:true and remaining state.uses)
in inventory, decrements its charges, and toggles target.state.lit. The
target's litText / extinguishedText / the lighter's lighterEmptyText
provide narration. Refuses politely on each error path.

Sets pendingDisambiguation on state and emits "Which X — A, or B?" using
each candidate item's short text. The existing disambiguation reply path
then re-issues the original verb against the chosen target.

Enables `light lamp with matches`, `use shears on vines`, and similar
multi-noun forms. Both the target and indirect noun must resolve;
otherwise the command falls back to unknown-noun.

Replaces the previous behavior of returning unknown-noun. The dispatcher
will use this in the next commit to prompt the player to disambiguate.

Allows `look at lamp`, `examine the letter`, `take a key`, `take an oil lamp`.
Stop-words are only removed from the head of the noun phrase, not from
anywhere in the middle.

Previously, clicking the theme button updated localStorage and the DOM but
not state.theme, so the engine's `theme` meta-verb toggled from stale state.
Theme is now exclusively UI/storage concern. Old saves with the field still
load; the field is silently ignored.

Drops redundant string[] casts in dispatcher paths and prepares the
TranscriptLine kind for the ending-screen render path.
