TEMP_REFERENCE/metakit renamed to metakit_jnorthrup: update references

The metakit checkout was renamed when the metakit_pooryorick variant arrived
beside it. Update the six reference sites (G-101 scope+detail, G-096 archive
note, suite_tcl90 README/build905.zig/suite.tcl vqtcl-removal comments) to
the new folder name. No functional change - comments and goal text only.

 Goal: a decided, demonstrated strategy for wrapping zig-built 8.6 runtimes into self-contained punk86-class kit executables in the absence of zipfs - candidate containers: the metakit/mk4vfs tclkit lineage, cookfs, and zipvfs-over-tclvfs boot - so the prebuilt third-party kit runtimes (tclkit86bi.exe, tclkit-win64-dyn.exe) can eventually be replaced by suite-built, provenance-carrying ones.
 Acceptance: the candidate containers are assessed and recorded here against punkshell's kit expectations (compatibility with make.tcl's 'kit' wrap path or a documented replacement path; boot-time vfs mount without an installed Tcl; loading binary dlls from or via the container; buildable from source under the zig-only policy); one strategy is demonstrated end-to-end - a kit wrapped from the suite-built 8.6 runtime boots on a path without any Tcl installation and runs a script from inside its vfs; the decision, rationale, and the follow-on work needed to reach punk86-kit parity are recorded in this file.
