perf(alias): avoid per-resolve split("*") in AliasUtils scan

[alexander-akait]

AliasPlugin's per-resolve scan (aliasResolveHandler) called
item.name.split("*") for every alias option on every resolve, allocating
an array on each iteration even though almost all aliases in practice
contain no * and the split's result was immediately discarded.

Replace with a cheap indexOf("*")-based check that only computes the
prefix/suffix slices when the wildcard branch actually fires. Semantics
match the original split("*").length === 2: wildcard iff exactly one
* is present in item.name.

Measured locally via the benchmark suite (wall-clock, n=10):
alias-wildcard-scan 471 -> 552 ops/s (+17.1%)
large-alias-list 836 -> 952 ops/s (+13.9%)

Adds a new alias-wildcard-scan benchmark case that stresses this
decision with 100 non-matching aliases + 1 wildcard + 1 exact match so
the wildcard-detection cost shows up cleanly on CodSpeed, separately
from the fixture-IO exercised by large-alias-list.
