G-083: activate (proposed -> active) - punk::args argument relations

Activation-freshness overlap survey (goals_xref score G-083) confirmed the
existing Notes already record the real relationships (G-053, G-072, G-084 -
all linked). G-167's back-pointer explicitly declares a deliberate non-overlap
with no sequencing constraint; remaining unlinked pairs are low-score
term-only siblings with no path overlap. No new Related: lines warranted.

This work is a prerequisite for G-084 (parsekey completeness), whose
cross-member -multiple combination decision should be made with this goal's
relations vocabulary in hand. G-053 (occurrence arity) is slotted before
G-084 in the same sequence at the user's direction.

 # G-083 punk::args argument relations: strict mutual exclusivity and parsekey-group integrity
 
-Status: proposed
+Status: active
 Scope: src/modules/punk/args-999999.0a1.0.tm (resolve/spec compiler, parse paths incl mash, arg_error/synopsis/usage renderers, errorcode vocabulary); src/modules/punk/args/moduledoc/tclcore-999999.0a1.0.tm (lsearch, clock clicks dogfood); src/tests/modules/punk/args/testsuites/args/ + testsuites/dev/ (GAP flips + new characterization)
 Goal: punk::args definitions can express hard mutual exclusivity - a per-argument -conflicts relation (keyed on parsekeys, checked only against received arguments so defaults never conflict) and an @opts-level strict mode making distinct-member co-occurrence within a shared-parsekey group an error - while legacy last-wins remains the default, so lsearch-class commands (grouped styles with pairwise incompatibilities like -sorted vs -glob/-regexp and -bisect vs -all/-not) parse and document faithfully without combinatorial @form explosion.
 Acceptance: parse raises a usage-style error with a structured errorcode (PUNKARGS VALIDATION optionconflict shape) naming both offending received arguments for -conflicts violations and strict-group co-occurrence, through both the ordinary and mash option paths with prefix abbreviations resolved before the check; define time rejects a -parsekey colliding with a distinct defined argument's name (parsekey_collides_with_defined_optname_GAP flips); legacy behaviour is untouched by default (full existing punk::args suite passes, including the pinned last-wins/prepend-defaults override idiom); the lsearch moduledoc models its documented incompatibilities with the new vocabulary and drops its "punk::args fixes required for grouped mutually exclusive options" caveat; usage/synopsis output for conflict rules is pinned by characterization tests.
