build: add run_magic*.sh launchers to run magic from the build tree Four configure-generated launch scripts let you run magic straight from the build directory without `make install`: * run_magic.sh -- GUI magic (Cairo/X11) * run_magicnull.sh -- batch / no-GUI (-dnull) * run_magic_gdb.sh -- magic under gdb * run_magic_valgrind.sh -- magic under valgrind magic resolves its runtime files through a single $CAD_ROOT root ($CAD_ROOT/magic/{sys,tcl}), but in the build tree they are scattered across build/ (generated tech, .magicrc, magic.tcl, tclmagic, execs) and source/ (colormaps, dstyles, glyphs, fonts, tcl scripts). On first run each launcher self-stages ${builddir}/CAD_DIR as a symlink tree in that layout (no copies, always current) via the shared scripts/magic_run_common.sh, exports CAD_ROOT=${builddir}/CAD_DIR, and execs the right binary. This pairs with the preceding commit that made the C launchers honor CAD_ROOT. magic_stage() is idempotent and re-runs on every launch. Most staged entries are files, but the bitmaps entry links a *directory*, so it uses `ln -sfn` (--no-dereference; also accepted by BSD ln): a plain `ln -sf` would, on a second run, dereference the existing symlink-to-directory and drop the new link *inside* the target -- a magic/bitmaps/bitmaps self-loop in the source tree that trips up find/tar/cp -r. Verified: ./run_magicnull.sh self-stages (30 sys + 24 tcl symlinks) and runs -- `tech load scmos` reports 13 planes -- straight from the build dir. gitignore covers the generated scripts and the CAD_DIR tree.
