refactor!: make BigInt-free PCG32 the default; suffix BigInt path with 64

The number-based fast variant is now the default API: createPcg32,
nextState, prevState, stepState, getOutput, randomInt, randomUint32,
randomList, plus the Pcg32 and RandomFn types.

The original BigInt-backed implementation is renamed to createPcg64
(plus nextState64, prevState64, stepState64, getOutput64, randomInt64,
randomList64, PCGState64, RandomFn64, CreatePcg64) and remains the
only path for non-default stream schemes (ONESEQ, MCG) and output
functions (XSH_RS, XSL_RR, RXS_M_XS).

src/fast.ts renamed to src/pcg32.ts. createPcg32 in tests was renamed
to createPcg64 throughout; old fast.test.ts renamed to pcg32.test.ts.

BREAKING: createPcg32(opts, state, streamId) -> createPcg32(state, streamId).
Callers using stream schemes or non-default output fns should migrate
to createPcg64. randomInt/randomList curried partial-application forms
are only available on the createPcg64 path.
