v0.5.2 - Register summary field rename

• register.resolve() returns count, not a field named entries holding a number.
  It collided when callers spread the result next to the entry array.

v0.5.0 - Pool look-through

• snapshot.take() looks through pools with readable share accounting.
• Look-through rounding dust stays with the pool so a snapshot still reconciles.

v0.4.0 - Snapshot and allocation

• allocation.allocateAccrual() for issuers that bump the multiplier instead of paying.

v0.3.0 - Corporate-action register

• register.build() flags duplicates, reversals and outsized steps.
• register.resolve() reports absolute and composed readings side by side.

v0.2.0 - Bytecode identity

• identity.resolveTicker() throws on ambiguity rather than returning the first match.

v0.1.0 - Fixed-point multiplier arithmetic

• Fixed-point multiplier arithmetic, BigInt throughout.
