Resolves a part of #11352.

Description

What is the purpose of this pull request?

This pull request:

• migrates simulate/iter/sine-wave test assertions from relative-tolerance (delta/tol/EPS) comparisons to ULP-based assertions using @stdlib/assert/is-almost-same-value, per [RFC]: Migrate math/base/special packages from relative tolerance testing to ULP difference testing (tracking issue) #11352.
• uses a single named ULP constant per test body, tightened to the minimum integer value that still passes over the full fixture set (verified deterministic across two consecutive test runs):
  • the function returns an iterator protocol-compliant object which generates a sine wave: ULP = 4
  • the function supports specifying the waveform period: ULP = 0
  • the function supports specifying the wave amplitude: ULP = 4
  • the function supports specifying the phase offset (left shift): ULP = 0
  • the function supports specifying the phase offset (left shift; mod): ULP = 0
  • the function supports specifying the phase offset (right shift): ULP = 0
  • the function supports specifying the phase offset (right shift; mod): ULP = 0

Hello! 👋

We've noticed that you've been opening a number of PRs addressing good first issues. Thank you for your interest and enthusiasm!

Now that you've made a few contributions, we suggest no longer working on good first issues. Instead, we encourage you to prioritize cleaning up any PRs which have yet to be merged and then proceed to work on more involved tasks.

Not only does this ensure that other new contributors can work on things and get ramped up on all things stdlib, it also ensures that you can spend your time on more challenging problems. 🚀

For ideas for future PRs, feel free to search the codebase for TODOs and FIXMEs and be sure to check out other open issues on the issue tracker. Cheers!

⚠️ Issue Reference Review

An automated check found potentially unrelated issue/PR references in this PR:

Reference	Assessment	Reasoning
#11352	suspicious	Issue #11352 is an RFC explicitly scoped to migrating math/base/special packages from relative-tolerance to ULP-based testing (its own instructions say to search for a package "in math/base/special"). This PR migrates tests for simulate/iter/sine-wave, which is outside the issue's stated scope.

Why this matters: GitHub automatically closes issues referenced with
closing keywords (Resolves, Closes, Fixes) when the PR is merged. Incorrect
references can accidentally close unrelated issues.

What to do:

• If the reference is correct, no action needed. This check may produce
  false positives.
• If the reference is incorrect, please update your PR description.

This assessment was generated by an AI model and is informational only.
