Replaces float-based lovelace arithmetic with BigInt throughout purchaseAsset
to avoid silent precision loss for NFT prices above Number.MAX_SAFE_INTEGER
(~9,007,199 ADA). The previous `as number` casts were TypeScript-only lies
that caused a TypeError at runtime; converting via Number() fixed the crash
but introduced silent rounding errors for large prices.

Changes:
- All fee and seller-payment calculations now use BigInt operators; quantities
  are only converted to string at the txOut boundary.
- Ceiling division implemented as (a * b + 9999n) / 10000n instead of
  Math.ceil(float), which is exact and matches the on-chain semantics.
- 1-ADA minimum fee floor is now guarded by priceBig > 0n so free listings
  (price = 0) no longer incur a spurious mandatory fee.
- lovelaceEntry guard replaces the !.quantity non-null assertion with a
  descriptive error instead of an opaque TypeError.
- Constructor validates feePercentageBasisPoint is in [0, 10000] and throws
  early rather than silently producing unbalanceable transactions.

cntools: raise main metadata file cap to 1024 bytes when extended field present (CIP-6)

CIP-6 raises the 512-byte main metadata file cap to 1024 bytes when the
file references extended metadata. Pools with longer descriptions that
also include the extended field currently can't register/update through
CNTools because the locally-built JSON crosses 512 bytes once the
extended URL is appended.

- Locally-built file: 1024-byte cap when meta_extended_option is set,
  512 otherwise.
- Downloaded file: peek for legacy `extended` or CIP-6 ext fields via
  jq; if any are present, allow 1024 bytes, else keep strict 512.
- Bump extended URL length check from 64 to 128 chars to match CIP-6
  (extDataUrl is 128 char max) and the main URL check that was already
  bumped to 128 in this same flow.
