Accept TRSL V1C1 (WP-0001-T06): objective Commercial Use definition

Bernd reviewed the License candidate and accepted it, conditioned on one
refinement to §1's "Commercial Use" definition: replaces the prior
circular definition ("use other than Noncommercial Use") with an
objective, billing-based trigger. Commercial Use now means billing a
customer for pre-conversion Software use, full stop - regardless of
whether the resulting payment is registered with the Trust Service.
Billing without recording the payment in the Target Ledger is Commercial
Use without a valid Commercial Entitlement, a Section 3 violation
addressed under Section 7 and, where applicable, the Enforcement Network.

This substantially resolves the affiliate/contractor/mixed-purpose/
public-sector ambiguity Appendix A item 1 flagged, since classification
no longer depends on who the customer is, only on whether they are
billed. A narrower residual item remains open: whether consumer-
protection law overrides this classification for an individual/sole-
proprietor customer in a given jurisdiction (the same recurring pattern
found across WP-0004's jurisdiction research).

Updates the document's status banner: condition 3 (human acceptance) is
now met; conditions 1 (specialist legal review) and 2 (full Appendix A
resolution) remain open - V1C1 is accepted as adequate briefing material
for counsel, not yet official Version 1.0. Marks WP-0001-T06 done and the
WP-0001 workplan finished (all 6 tasks complete). Updates
OpenQuestions-WorkingDefaults.md Q2, README, and CONTRIBUTING.md to match.
