add goal G-037 (proposed): propagate platform vendor libs into kit vfs lib_tcl trees via make.tcl
Motivating case: the tcludp 1.0.13 upgrade for G-036 - libs, vfscommonupdate
and project all completed while every kit vfs still bundled udp 1.0.12,
requiring manual copies into each vfs lib_tcl9 folder.

Goal: the Tcl 9-only wedge - a worker thread that has used a tcludp syslog socket stops servicing its event queue (timers, thread::send) when the punkshell process is console-attached, the proximate trigger of the piped-stdin exit/quit hang - is root-caused to a named component (Tcl 9 Windows console driver, tcludp, Thread extension, or a specific interaction) with the smallest demonstrating repro, so the user can decide on and manually file an upstream report.
Acceptance: a repro reduced to the smallest ingredient set demonstrates the wedge on Tcl 9 Windows and its absence on Tcl 8.6 under identical conditions (target: plain Tcl + Thread + tcludp with no punk modules; if a punk component proves essential, the repro thereby pins which one); the wedge mechanism is identified and written up in the detail file (which wait never returns and why - e.g. via native thread stacks of a wedged specimen); before any upstream report the repro is re-verified against a Tcl 9 built from current core sources (per G-005 build capability - the shipped kit's 9.0.2 may carry an already-fixed bug), with the outcome recorded in the detail file; upstream filing itself is the user's manual step and not gated on this goal; the in-context batch harness (hidden-console piped-stdin runs scoring worker heartbeats, listings in the detail file) is retained as the regression check, with the 2026-07-08 baseline (punk902z run-2 syslog workers wedged 4/4, punksys alive 4/4) reproduced before and resolved after any fix.
### G-037 [proposed] Propagate platform vendor libraries into kit vfs lib_tcl trees via make.tcl
Scope: src/make.tcl (new or extended step), src/vendorlib_tcl8 + src/vendorlib_tcl9 (sources), src/vfs/<kit>.vfs/lib_tcl8 + lib_tcl9 (targets), punkcheck tracking
Goal: platform-specific vendored binary packages under src/vendorlib_tcl<N>/<platform> reach the kit vfs lib_tcl<N> trees through a make.tcl step instead of hand-copying - updating a vendored package becomes a vendorlib drop plus standard build invocations (motivating case 2026-07-08: tcludp 1.0.12 -> 1.0.13 for the G-036 wedge fix - `libs`, `vfscommonupdate` and `project` all completed while every kit vfs still bundled udp 1.0.12, requiring a manual copy into each vfs lib_tcl9 folder).
Acceptance: with a newer package version placed under src/vendorlib_tcl9/<platform>, one documented make.tcl invocation updates the participating src/vfs/*/lib_tcl9 trees - installing the new package and removing or explicitly retiring the superseded version (no silent mixed-version provision, per the G-035 concerns) - with punkcheck-tracked provenance; which vfs folders participate is explicitly declared per kit rather than blanket-copied (kit vfs package sets may intentionally differ), with the declaration mechanism recorded (candidate home: the G-024 mapvfs toml); a subsequent `make.tcl project` yields kits loading the new version (provable via the tcludp case: built punk902z reports `package require udp` == 1.0.13 with no udp1.0.12 folder remaining in its vfs); the lib_tcl8 tree gets the same treatment or an explicit exclusion rationale in the goal record.
