Add usage examples and reference documentation for the Conway
governance (CIP-1694) local-state queries.

- Add drep-state, committee-state, proposals, and vote-delegatees
  subcommands to the examples/state-query CLI, alongside the existing
  local-state queries. Usage examples live under examples/ rather than
  in test files so they are easy to find without reading the test suite.
- Expand doc comments on all governance query methods (GetConstitution,
  GetGovState, GetDRepState, GetDRepStakeDistr, GetCommitteeMembersState,
  GetFilteredVoteDelegatees, GetSPOStakeDistr, GetProposals,
  GetRatifyState) to cover when to use each, the response structure, and
  the Conway-era requirement.

Re-processing the off-chain metadata of an already-stored voting anchor
duplicated its child rows (off_chain_vote_drep_data, off_chain_vote_author,
off_chain_vote_reference, off_chain_vote_external_update,
off_chain_vote_gov_action_data). The parent insert used ON CONFLICT DO
UPDATE ... RETURNING id, so a re-fetch returned the existing id, and the
children - which have no uniqueness and were plain-inserted - were written
again.

Make insertion idempotent: insertBulkOffChainVoteDataReturningNew uses ON
CONFLICT DO NOTHING RETURNING (voting_anchor_id, hash, id) so only newly
inserted parents come back, and the orchestration inserts child rows only
for those, matched by natural key. Adds a WithResultBulkColumns result mode
for a custom RETURNING column list. Prevents new duplicates; existing rows
on synced DBs are unaffected.

Adds a regression test (cardano-db test-db) asserting a re-fetch creates no
duplicate child rows.
