G-031: split the monolithic vfs main (punk_main.tcl: 1190-line apply
block - ~1060 lines boot machinery, ~100 lines dispatch tail) into a
layout-owned boot core (shipped via _vfscommon.vfs, sourced by
vfs-relative path since no package paths exist at boot; pull-updatable
per the G-027 ownership model) and a thin project-owned main declaring
app subcommands at commented customization points. Fork cost measured:
tomlish_main.tcl carries ~20 custom lines on a stale 500-line 2025
vintage copy; project_main.tcl (901 lines) same at template vintage -
boot improvements never reach derived projects. Acceptance: behaviour
parity across dispatch cases and vfs types, project subcommand added by
editing only the thin main (tomlish the proving ground), boot core
versioned/reportable (G-025).
G-032: the default dispatch defines subcommands via punk::args - tabled
-help enumerating built-in and project-registered subcommands, parsed
options with tabled usage errors (script/G-015 or version-report/G-025
as first candidates), G-030 degradation rules (guarded require; parsing
falls back to switch semantics, help to a plain list; rendering degrades
independently). Parked decision: the silent unknown-arg->script
reclassification should stop swallowing typos (candidate rule:
reclassify only when the argument names an existing file).
