Implements the ProfilerPlugin that taps the resolveStep sync hook to
record per-hook entry timestamps, maintains a frame stack for duration
tracking, and delivers profile data via resolveContext.profile callback
or factory-level profileCallback.
The \`profile\` option is added to ResolverFactory.createResolver options:
- \`profile: true\` enables profiling with per-call resolveContext.profile
- \`profile: (data) => {}\` enables profiling with a factory-level callback
- profile is propagated through createInnerContext for nested resolves
Changes:
- lib/ProfilerPlugin.js: new plugin with frame-stack timing
- lib/ResolverFactory.js: profile option + wiring
- lib/Resolver.js: profile field in ResolveContext typedef
- lib/createInnerContext.js: propagate profile to inner context
- lib/index.js: export ProfilerPlugin via lazy getter
- types.d.ts: ProfileData, ProfileHookEntry, ProfilerPlugin types
- test/profiler.test.js: 6 tests covering all delivery paths
