0.12.5

Fixed

• v-if and v-for leaked everything they had ever rendered. Both take
  their element out of the document and keep it as the thing they clone from.
  The cleanup for that element — the effect scope runDirective registered on
  it — is keyed by that element, and destroy() walks live children only. Once
  detached, nothing ever reached it: the scope was never stopped, and it held
  the template, every rendered block and every node inside them.

  Fifty mount-and-destroy cycles per size, heap forced between samples, retained
  per cycle:

  rows	before	after
  50	393.6 KB	11.1 KB
  100	749.7 KB	6.5 KB
  200	1498.4 KB	13.0 KB

  The old figure doubles with the list because it was proportional to what had
  been rendered; the new one does not grow, and what remains is noise.

  It cost time as well as memory: the v-if toggle benchmark went from 5,683 ms
  to 3,079 ms once the garbage stopped accumulating. The project's own memory
  suite could not finish before this — it exhausted a 3.8 GB heap and took the
  rest of the run down with it — and now completes all thirteen cases.

  The hypothesis was already written down in benchmarks/memory/index.mjs, with
  an A/B pair built to measure it. What was missing was routing destroy() to
  the detached templates, which it now does by recording them against the parent
  they left.

Changed

• The comparison numbers in both READMEs were re-measured, and the honest
  reading changed with them. Create improved in absolute terms, 97.70 ms to
  80.81 ms, while the position moved from third of seven to fourth, because the
  other frameworks measured differently in the same run. Preact, Solid and
  Voodoo now finish within 0.4 ms of each other on a thousand-row create, which
  is a three-way tie a ranking column cannot express. Both tables say so.

• The teardown chart is generated from the measurement rather than hand-
  edited, the way the framework comparison already was.
  node --expose-gc scripts/measure-teardown.mjs builds both versions, measures
  them, restores the source, and writes the JSON that
  scripts/chart-teardown.mjs draws.
