main now has #1286 and later collector changes. Resolved in scr_cycle.c:
the scheduled collection point collects the nursery, then notes the
live-count fall (death rule). Semantic fixes for the new main code:
a full pass's markGray no longer overwrites a young object's `buf` (its
nursery index) with the component number, and a nursery collection
refreshes the death rule's live reading at its end so the young garbage
it frees does not count as deaths outside passes. Formats the runtime
pack matrix test.

SCRIPTC_YOUNG_NURSERY=1 at compile time makes an executable allocate
traced, program-owned class instances and records young and link the
collector unit built with SCR_YIN (a runtime pack variant of
scr_cycle.c; libraries never get it). The emitted constructor lists the
object in a per-thread nursery and marks its header: generation
SCR_CYC_YOUNG and its nursery index under the buffered bit, so every
existing release path treats it as a buffered candidate (no call while it
stays alive; scr_cyc_on_dead takes it out of the nursery at its death).
A nursery collection (whenever 4096 young objects are live, at collection
points, before full sweeps and limited passes) counts each young object's
references from other young objects, marks from the objects whose count is
below their reference count (referenced from outside the nursery: stacks,
globals, older objects, runtime structures, FFI, fibers, coroutine
frames), frees what stays unmarked, and gives up the dead set's outgoing
edges after the teardowns. The counts are recomputed at every collection
instead of maintained by a store barrier, so soundness rests only on the
invariants trial deletion already needs. Survivors join trial deletion's
nursery and outside roots become candidates; trial deletion walks young
objects it reaches as nursery-level objects. Per-type admission statistics
send types that do not die in young cycles back to trial deletion for a
while. Publication takes young objects out of the nursery. The RC audit
build checks nursery membership and counts at every collection.
With the flag off, the compiler emits and links exactly what it did
before (249 programs and the self-hosted compiler compared
byte-identical). Measured with the flag on: cg-rings -38%, cg-pairs -27%,
the runtime suite geomean -0.3% (published-graphs +3.4%), the self-hosted
compiler neutral; shapes whose cycles go through arrays or closures
(phase 2) pay without gaining.
