bootsupport manifest: commandstack pulled from minted root modules

commandstack is first-party (src/modules source, minted to root modules/
since the module left vendormodules) - the manifest still pointed at
src/vendormodules, which carries no commandstack-*.tm, so bootsupport
was frozen at the stale 0.3/0.4 copies. Repoint to base `modules` (the
packagepreference pattern) in include_modules.config and the tclpackages
toml record so `make.tcl bootsupport` promotes the minted 0.6.0.
Layout manifest copies sync on the next make.tcl modules run.
