The IDO RPC record no longer leaks internal txchain row ids. Drop the
txchain_entrypoint field entirely, and change txchain_head from the
internal ido_txchain.id to the head record's txid (display hex).
list_idos and get_ido_by_offering_token_id resolve this in a single
query via LEFT JOIN ido_txchain ON head_tx.id = ido.txchain_head; a
NULL head yields null. Adds tests for both the resolved and null cases.

Rename ido.id -> ido.internal_id in the schema and IdoDBRecord, and
expose the preinit_txid hex as the public "id" in all RPC responses.
Public API shape:
- IdoRpcRecord.id: i64 -> String (hex of preinit_txid). preinit_txid
field is preserved unchanged.
- IdoEntryRpcRecord.ido_id: i64 -> String (hex of parent preinit_txid).
- IdoTxChainRpcRecord.ido_id: i64 -> String (hex of parent preinit_txid).
- IdoTxChainRpcRecord gains ido_internal_id: i64 (debug endpoint only).
- Routes /<id>/entries and /<id>/txchain accept the preinit_txid hex
as the path id; returns 404 IDO_NOT_FOUND on miss.
Internals:
- New lookup_internal_id_by_preinit_txid helper.
- list_ido_entries / list_ido_txchain take preinit_txid_hex as input
so the caller (which already parsed it from the path) avoids the
extra "preinit_txid by internal_id" lookup.
- Child table FK columns (ido_entry.ido_id, ido_txchain.ido_id) keep
their names; only the parent PK and field accesses were renamed.
Notes:
- Breaking API change for /ido/* endpoints. Clients reading "id" or
"ido_id" as integers must switch to strings.
- ido.db has no migration framework: drop the file and re-index on
deploy.

List every active TokenToken pool (no pair filter) so the frontend can
present the set of pooled token pairs without probing each candidate pair.
Mirrors db_active_pools_for_pair minus the pair WHERE clause; served at a
distinct /pools path (the param'd /pool/active already matches param-less
requests via its Option guards, so reusing it would collide).

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

This makes the application fully async; freeing web server threads to
handle new connections when waiting on SQL queries.
Additionally sqlx will allow easier move to a different database if
needed in the future.
Includes some SQL optimizations as well (slow queries more easliy identifiable
with sqlx).
The previous commit tried to query bcmr_data table from the crc20
database connection, but bcmr_data exists only in the bcmr database.
Fix by introducing STATE_SKIP_HAS_BCMR to mark tokens that have BCMR
data. The CRC20 fetcher now queries the bcmr database separately to
find candidates with BCMR data, marks them in the crc20 database, and
skips them in future iterations.
- Refactor update_changes_score_volume_and_ranking to use read connections
for read/compute phases, only acquiring write connection for final writes
- Change first_pool_creation to use try_get() for opportunistic caching,
preventing thread exhaustion if write pool is busy
- Add linter to flag blocking _w.get() calls in RPC handlers
Migrate all 32-byte hash fields from TEXT (64-char hex) to BLOB
(32 bytes) for ~50% storage savings on hash columns.
Changes:
- Add src/db/blob.rs with ToBlob/FromBlob traits for hash types
- Update all table schemas to use BLOB for hash columns
- Replace .to_hex() with .to_blob() for DB inserts
- Replace ::from_hex() with ::from_blob() for DB reads
- Use SQL hex() function where API responses need hex strings
- Bump DB_VERSION from 4 to 5
Affected tables: tx, pool, pool_history_entry, utxo_spending,
utxo_funding, user_action, auth_chain_entry, bcmr_data,
bcmr_failure, bcmr_well_known, crc20, crc20_candidates,
delphi_entry, cached_token_metrics
Fixes#1
When a token has both an auth_chain_entry (without BCMR) and a CRC20
entry (with name/symbol), the dedup logic now keeps the metadata
instead of returning NULL.
Introduce a shutdown flag and Rocket fairing that signals background
threads to exit cleanly when Ctrl+C is pressed. Affects the indexing
thread, metrics updater, and block receiver loop.
Remove errant UNIQUE INDEX on (utxo, txid) that conflicted with the
PRIMARY KEY (token_id, utxo, txid). A single transaction can update
auth chains for multiple tokens, requiring the same (utxo, txid) pair
to exist with different token_ids. The unique index blocked this.
The index was also unnecessary - EXPLAIN QUERY PLAN shows the PRIMARY
KEY index is used for all bcmr_failure lookups.
Add test covering multi-token failure recording.
