  1. Add Affinity-local Bounds helper and clarify cycle/time semantics 

    Add a Bounds class to validate sizes/offsets without taking a
Chronicle-Core dependency (this module is below Core in the
dependency graph). The class name and method signatures mirror
Chronicle-Core's Bounds so call sites read consistently across the
project.

Use the helper at the four sites where a SIZE-meta-typed receiver
is computed from arithmetic that downstream tooling cannot easily
prove non-negative:
  - LinuxHelper.SIZE_OF_CPU_SET_T          (constant expression)
  - PosixJNAAffinity.cpuSetSizeInLongs    ((procs + 63) / 64)
  - PosixJNAAffinity.cpuSetSizeInBytes    (longs * 8)

Rename time-typed locals so the time meta-type is explicit:
  - MicroJitterSampler.sample: `end` -> `endNs` (future timestamp)
  - JNIClock.estimateFrequency: `end`/`start0`/`end0` -> `endNs`/
    `startCycles0`/`endCycles0`. `startCycles0` is wrapped with
    `Bounds.requireOffset` because rdtsc() is always non-negative
    within a process lifetime.
