feat(governance): v0.0.34 Phase 5 FULLY COMPLETE — 5.3-5.8 refinements consolidated 🎉🎉🎉

Phase 5 GOVERNANCE FULLY COMPLETE end-to-end canonical. 5.3-5.8 refinements
consolidated single ship canonical. AI advisor flag system (5.6) + Council
veto override 4/5 community supermajority (5.5) + Emergency referendum 48h
fast-track (5.7) + Treasury disbursement (5.8) + voting period constants (5.3+5.4).

## Phase 5.3+5.4 constants canonical

- DEFAULT_VOTING_PERIOD_BLOCKS = 201,600 (14 days × 24h × 600 blocks/h @ 6s)
- EMERGENCY_VOTING_PERIOD_BLOCKS = 28,800 (48h × 600 blocks/h)
- council_emergency_threshold ceiling 5/7

## Phase 5.5 Community override canonical

- override_council_veto dispatchable (7-step canonical)
- 4/5 supermajority ceiling threshold (override_supermajority_threshold const fn)
- OverrideVotes StorageDoubleMap + OverrideStakeTotal cached
- Events::CouncilVetoOverridden + Errors::ProposalNotRejected/AlreadyOverrideVoted/OverrideThresholdNotMet

## Phase 5.6 AI advisor system canonical

- AdvisorFlags StorageMap presence-based
- mark_as_advisor + unmark_as_advisor dispatchables (ensure_root)
- cast_vote canonical EXTENDED: AdvisorMayNotVote enforcement (humans-only vote)
- Events::AdvisorFlagged + AdvisorUnflagged + Errors::AlreadyAdvisor + NotAdvisor

## Phase 5.7 Emergency referendum canonical

- submit_emergency_proposal canonical (council-only + 5/7 council pre-approval)
- Fast-track 48h voting period vs 14 days
- Events::EmergencyProposalSubmitted + Errors::InsufficientCouncilEmergencyApprovals

## Phase 5.8 Treasury disbursement canonical

- Treasury StorageValue<u128> Foundation balance
- treasury_deposit (ensure_root helper) + treasury_disbursement (6-step canonical)
- Requires ProposalStatus::Approved (governance ratification)
- Events::TreasuryDisbursed + Errors::TreasuryInsufficientBalance + ProposalNotApproved

## Phase 5 dispatchables canonical inventory

12 total dispatchables (Index 0-11): submit_proposal + cast_vote + finalize_proposal
+ Council mgmt (add/remove) + veto + advisor mgmt (mark/unmark) + override +
emergency + treasury (disburse/deposit).

## Verification

- cargo build --release -p origin-chain-node 5.17s clean
- cargo test -p origin-chain-governance — 42 tests verde, 0 failures
  (10 lifecycle + 7 Council mgmt + 5 Council veto + 3 Advisor + 3 Override + 3 Emergency + 4 Treasury + 5 standalone + 2 auto)
- cargo test --workspace — 202 tests verde, 0 failures
