feat(end-state): a gate that counts the distance to "Voyage is finished" - red

Voyage now has a destination that can fail: finish the phase-2 pipeline, close the open
experiments, freeze. This adds the gate that measures the distance to it. Nothing is
fixed or removed here; every defect and every removal is its own change.

scripts/end-state-gate.mjs counts four tallies; finished = all four at 0.
  defects         listed in scripts/end-state-registry.json, each with a runnable check
  experiments     listed in the registry, each with a runnable check
  dormant-agents  spawnable agents no commands/*.md references (structural, word-bounded;
                  files carrying the reference-document marker are excluded)
  decisions       open operator decisions in the local STATE.md, by a fixed marker
Exit 0 green, 1 red, 2 usage/registry error. `--json` for machines.

Fail-closed by construction: an entry with no check, or whose check cannot run (missing
file, empty glob, missing section), is NOT FELLABLE and counts as open; a missing STATE.md,
a missing section, or an unmarked list item in it makes the decisions tally n/a, which
keeps the gate red. The decisions row is therefore n/a in any clean clone.

Result today (clean export of the index): RED, 0 of 4 tallies at 0 -
defects 7 of 7, experiments 3 of 3, dormant agents 1 of 20, decisions n/a.
With the local STATE present: decisions 11 of 12.

Verified in both directions: 18 fixture tests pin each tally at 0 and above 0. Each of the
10 registry checks was measured open on this tree and closed after a simulated fix on a
throwaway copy (10 of 10). That run caught a too-broad D-03 check - Phase 4's legitimate
entry-condition skip also matched - which is now scoped to the Phase 7 section.
Suite 1041 -> 1059 (1057/0/2), also run on the clean export.
