docs(P00): grill v0.8 plan — PROCEED-WITH-CONDITION (4 binding fixes applied)

GRILL_v0.8.md (30KB): 9-axis adversarial review, overall verdict
PROCEED-WITH-CONDITION (confidence 0.78). 7 PROCEED + 4
PROCEED-WITH-CONDITION + 0 REPLAN findings.

4 binding plan changes applied to PLAN_v0.8.md:
  #1 T02.6 relabeled as v0.6 ship-defect bugfix (not v0.8 feature);
     P04 audit must record ship-defect closure
  #2 T02.9 doctor proxmox parity — P02 not complete until both
     bootstrap + doctor callbacks use capture-fix wrapper
  #3 T01.6 cli coverage escape valve — ship at 65% if 70% not reached
     after Wave 2 (RESEARCH §1.4 flags 55-65% realistic); do not block
     P02/P03 on the last 5%
  #4 T03.1 verify-reqs regex substring-tolerant (matches v0.2 header
     variant) + reverse-direction assertion (REQUIREMENTS Complete ↔
     ROADMAP COMPLETE); scope note: doc-vs-doc drift only

T02.10 case 7 added (known_hosts pre-populated v0.6→v0.8 migration
path). No escalations; all axes resolved at confidence ≥ 0.60.
