Fixes the constructed-definition indent leak user review spotted in
'make.tcl help' output (@cmd -help Description first line rendered less
indented than continuations): HELPTEXTS and the inline shell/help/toplevel
help values are now block-form (first value line whitespace-only) with a bare
@normalize in every constructed definition, per G-045's preferred style. The
braced option fragments never leaked (literal block-shaped parts get
file-style normalization) and head-form values are contractually untouched by
@normalize. Also adds a define-time capability probe (punk::args::get_spec on
representative ids inside the guarded block) so a stale punk::args that
accepts the raw text but cannot resolve a mechanism (e.g pre-@normalize
snapshots) degrades to the plain fallback immediately instead of erroring at
first parse.
AGENTS infrastructure for future documentation work: src/modules/AGENTS.md
"Documentation And Comments" gains a "punk::args definition authoring
ergonomics" subsection (G-045 mechanisms: @normalize + block form for
constructed defs, -unindentedfields, -& record continuation, container
quoting rules; plus the G-030 lessons: explicit @form -synopsis for
script-level ids, -optional 0 for pointed choiceviolation errors);
src/AGENTS.md cross-references it and names ::punkboot::argdoc as the
in-tree constructed-def exemplar. Follow-up recorded in the G-030 archive.
Verified: flush Description rendering for toplevel/subcommand/shell/help
usage; dispatch, degraded mode (PUNKBOOT_PLAIN) and usage-error paths
re-verified; layout make.tcl copies re-synced via 'make.tcl bootsupport
-confirm 0' (punkcheck channel); goals_lint unchanged (only the pre-existing
G-078/G-081 index-mirror findings).
