conductor(track): Mark intent_dsl_survey_20260612 complete

Three files updated to close out the track:

1. state.toml — all 28 tasks marked completed with their commit SHAs;
   current_phase = complete; all 14 verification flags = true; added
   deliverable_summary section pointing at report_v1.1.md, reportreview.md,
   and the 5 research/ sub-reports.

2. metadata.json — status: complete; added deliverable_v1_0, review,
   and final_commit fields.

3. tracks.md — track #23 heading now reads 'COMPLETE: c7e92896';
   added a 'Status: 2026-06-12 — COMPLETE' line summarizing the
   v1.1 deliverable (1301 lines, 7 sections + 9-subsection appendix,
   42-verb vocab, 8 prior-art clusters, 14-grammar primitives, 4
   hardware anchor claims, 10 AI-agent properties, 8 open questions).

This is the final bookkeeping for the track. nagent v2.2 can now
reference the report's Section 6 (AI-Agent Properties) and Section 7
(Open Questions) for its 'Future-Track Candidate #4: Intent-based
DSL' planning.
