Add an OP_RETURN "BCMR" prefix filter to the rostrum mempool.get pass and
index matching txs in update_mempool with the all-zeros sentinel blockhash
(same pattern as oracle). A newly registered BCMR becomes the auth head and
is downloaded immediately; the confirming block re-stamps the entry with
its real blockhash in place.
- insert_authheader: INSERT OR REPLACE -> upsert. REPLACE deletes the row,
cascading away downloaded bcmr_data on every mempool->confirmed upgrade.
- update_mempool drops sentinel entries whose tx left the mempool (evicted
or replaced), so stale auth heads never linger.
- clear bcmr mempool state at startup; always-run migration adds txid and
blockhash indexes on auth_chain_entry for the per-pass lookups.
Auth chain transfers without a BCMR output still index at confirmation.

- electrum mempool fetch gains an ido filter: state machine spends
(IDO_SIGNATURE in scriptsig) union preinit announcements
(IDO_PREINIT_ANNOUNCEMENT_SIGNATURE in scriptpubkey)
- split tx scanning out of index_block into index_txs and add
index_mempool, which indexes with a -1 sentinel height;
txchain_trim_tracker leaves negative heights alone and the real
height replaces the sentinel once the tx confirms in a block
- block indexing now skips re-creating an ido already seen in the
mempool, only updating its tracker height
- mempool txs are kahn-sorted so txchain parents index before children

Migrate off the deprecated bitcoincash 0.29 API (Amount/Version types,
FromHex -> FromStr/parse, non-exhaustive Network) across the indexer and
tests.
Add indexing of native token-A <-> token-B (TokenToken) AMM pools:
- tokentoken_pool / tokentoken_pool_history_entry tables in cauldron.db,
created via an always-run idempotent migration (no DB_VERSION bump, so
existing databases upgrade in place)
- block-path indexing sharing the cauldron write transaction and reorg
undo, with creation/swap/withdrawal state tracking and reserve deltas
- mempool indexing: electrum mempool.get filters on the tokentoken
contract code (spends) and the CONJURE op_return hint (creations);
first_seen_timestamp reconciles with mtp on confirmation
- RPC endpoints /tokentoken/pool/active (pair lookup, order-insensitive)
and /tokentoken/tokens
