docs(adr): ADR-0105 status flip — Phase 2 D8/D9 implemented, D8's role channel closed by ADR-0108

The status line still read 'Phase 0/1 implemented' while both Phase 2
product decisions had landed on 2026-07-28: D8 end-to-end (#3645 host seam,
#3663 placement engine, #3674 my-delegable-scope, #3695 issuer-grant
resolution, #3722 delegated_admin + invitation role cap closing #3697,
#3767 sys_member governed) and D9 (#3824, refusal path restored in #3873),
with the D9 section already amended in-PR. Cross-reference ADR-0108, which
closes the membership-role vocabulary D8's placement model replaces.

Tracking: #3541
