shoney.arickathil eb0095428d fix: Text is an owned value copied at every boundary (executable plan, Task 1)
Measured on the workload's supervisor mode, eight seconds, clean SIGTERM exit:
run 1 051 040 B in 24 allocations -> 2 112 B in 19; watch 128 B in 2 -> 64 B in
1. corpus 71/0, woc runtest 565/0, wovm unit gates green, just log-watcher 6/0.

- owner.ml: `oclass_of` called `Text` a builtin scalar, so it was Copy and NO
  Text local was ever dropped — that, not the missing stdlib table, was the
  leak. Text is now Owned, which forces an answer for what it does at an
  ownership boundary, and the answer is uniform: it is COPIED. Into a
  container (push/set/`m[i] = v`, already true), into a field (SETF), out of a
  function (return), into a binding (`let s = other`), and into a loop cursor.
  The source keeps its value; a freshly built Text stays the caller's and is
  dropped at the site
- owner.ml: resolve_callee answers for three shapes it never knew — reserved
  stdlib members, builtins, and a class's `static` members — so their results
  get a type, an owner and a drop
- vm/builtin: WO_B_TEXT_COPY, the one new builtin the rule needs; SETF copies a
  TEXT field in; emit copies a Text read out of a container, bound from a
  place, returned from a place, or loaded into a cursor, and drops a freshly
  built one after a copying store
- sysio.c: fs.read_all/net.read allocated their cap then relabelled the buffer
  with the short length — but wo_str_free sizes a block by its len (no size
  headers, obj.h), so a 1 MiB buffer wearing a 30-byte length went onto a
  32-byte free list and never came back. They copy out at the true size now
- two regressions the corpus caught, fixed in the same pass: a @gc value read
  out of a container is a plain borrow, not an rc-counted alias; and push's @gc
  escape is keyed on "push is not a user-declared fn" rather than "the callee
  did not resolve", which stopped being true once builtins resolved
- docs: Task 1 closed in the executable plan with its before/after numbers, and
  the status board's item 1 records the deeper root cause
