Rename *-magic.tcl scripts to *-tcl.tcl to match the -tcl.js test naming
convention. Delete the old bare-command pcell.tcl (used cellname create,
no magic:: prefix) and promote pcell-magic.tcl to pcell.tcl.
Fix misleading comment in magicWasm.c: Tclmagic_Init only bootstraps the
interpreter; magic:: commands are registered separately by
TclmagicRegisterCommands after magicMainInit. Align comment block
dashes in TclmagicRegisterCommands to match tclmagic.c style (62 dashes).
Replace intubun/tcl references in build scripts and CI with tcltk/tcl to
match the actual pinned repo in npm/tcl.ref. Also run both test suites
when build.sh is invoked with --test.
All non-TCL tests (extract, gds, drc, cif) now also run against the TCL
variant using magic::-prefixed Tcl scripts. A new PCell test generates
two parameterized rectangle cells and verifies their GDS output.
The CI workflow runs npm run test:tcl after the TCL build and saves the
generated output files as an artifact.
