deps(deps-dev): bump bitcoinjs-lib from 6.1.7 to 7.0.1

[dependabot]

Bumps bitcoinjs-lib from 6.1.7 to 7.0.1.

Changelog

Sourced from bitcoinjs-lib's changelog.

7.0.1

added

• crypto: Restore ripemd160, sha1, and sha256 hash helpers (#2248)
• p2ms: Support up to 20 public keys for n-of-20 multisig (previously capped at 16). This is relevant for P2WSH-wrapped multisig where the P2SH script-size limit does not apply. (#2297)

fixed

• psbt: Remove unnecessary tapInternalKey check for signature validation of taproot inputs (#2270)
• Bump valibot dependency (#2308)

7.0.0

breaking

• Buffer → Uint8Array: All public APIs now use standard Uint8Array instead of Node.js Buffer. This affects all payment types, Transaction, Psbt, Block, and script modules. Buffer (a Uint8Array subclass) is still accepted as input, but return types are now Uint8Array. (#2161)
• Transaction values: number → bigint: Transaction.Output.value changed from number to bigint. Psbt output values, Psbt.getFee(), and witnessUtxo.value are all bigint now. Update your code: value: 10000 → value: BigInt(10000) or value: 10000n.
• typeforce → valibot: Runtime type validation switched from typeforce to valibot. All typeforce re-exports removed (Buffer256bit, Hash160bit, Hash256bit, Number, Array, Boolean, String, Buffer, Hex, UInt8, UInt32, BufferN, Null, oneOf, maybe, tuple, Function, Satoshi). Replaced by valibot schemas (Buffer256bitSchema, Hash160bitSchema, Hash256bitSchema, BufferSchema, HexSchema, UInt8Schema, UInt32Schema, SatoshiSchema, NBufferSchemaFactory).
• ESM support: Package is now dual CJS/ESM. Added "type": "module" and exports field in package.json. CJS files use .cjs extension. Internal import paths now require .js extension.
• Node.js ≥ 18 required: Minimum Node.js version bumped from 8 to 18.
• Dependency major bumps: bip174 2.x → 3.x, bs58check 3.x → 4.x, varuint-bitcoin 1.x → 2.x.

added

• uint8array-tools dependency for cross-platform Uint8Array utilities
• valibot dependency for runtime type validation
• toXOnly exported from psbt/bip371
• Taproot multisig with verified unspendable internalPubkey example
• Better error message when signing a transaction without outputs

changed

• Coverage tooling switched from nyc to c8
• TypeScript execution switched from ts-node to tsx
• Fix tx version read/write to use uint32 instead of int32

fixed

• Fix multisig taproot example's provable nonce calculation
• Various typo fixes

Avoid upgrading bitcoinjs-lib before bigint migration

Bumping bitcoinjs-lib to 7.0.1 introduces a breaking runtime API change (Transaction output values are now bigint), but this repo’s BTC test helpers still build transactions with numeric values (e.g. _start_tx_builder in packages/sdk/src/__test__/utils/helpers.ts calls tx.addOutput(..., value) and tx.addOutput(..., changeValue) where both are numbers). With this version bump, those code paths will throw during BTC signing/address tests instead of producing reference transactions, so CI/test workflows that exercise these helpers will regress until values are converted to bigint.
