Failing run: https://github.com/stdlib-js/stdlib/actions/runs/28921300699 (job: Lint Changed Files, step: Lint TypeScript declarations files)

Symptom: stdlib/tsdoc-declarations-doctest ESLint rule failed with Expected entries [0,~0.707,~0.707,0,0,0,0,0], but observed [0.7071067811865476,0.7071067811865475,0,0,0,0,0,0] at lines 97 and 189.

Root cause: the cosqi/sinqi doc examples documented the twiddle-factor slice with a leading 0 before the two ~0.707 entries; the actual runtime output places the two ~0.707 entries first, with no leading zero.

Fix: corrected both examples to [ ~0.707, ~0.707, 0, 0, 0, 0, 0, 0 ], verified against the real output of cosqi/sinqi.

Disclosure

If you answered "yes" to using AI assistance, please provide a short disclosure indicating how you used AI assistance. This helps reviewers determine how much scrutiny to apply when reviewing your contribution. Example disclosures: "This PR was written primarily by Claude Code." or "I consulted ChatGPT to understand the codebase, but the proposed changes were fully authored manually by myself.".

This PR was written primarily by Claude Code as part of an automated CI-failure triage and fix routine, based on live GitHub Actions job log analysis and direct execution of the affected code to confirm expected output. The fix was reviewed by three independent automated review passes (correctness, regression scope, style/conventions) before being proposed here; all approved.

Generated by Claude Code

The job `Lint Changed Files` failed on develop with the
`stdlib/tsdoc-declarations-doctest` ESLint rule reporting a mismatch
in `docs/types/index.d.ts`:

  Expected entries [0,~0.707,~0.707,0,0,0,0,0], but observed
  [0.7071067811865476,0.7071067811865475,0,0,0,0,0,0]

Root cause: the `cosqi` and `sinqi` TSDoc examples documented the
twiddle-factor slice as starting with a leading `0` followed by the
two `~0.707` entries, but running the actual code places the two
`~0.707` entries at the start of the slice with no leading zero.
This commit corrects both examples to `[ ~0.707, ~0.707, 0, 0, 0, 0,
0, 0 ]`, matching the real output (verified by directly executing
`cosqi`/`sinqi` against a workspace array and inspecting the
resulting twiddle-factor slice).

Closing, as this isn't just about doctesting. This is part of an ongoing fix which will be addressed in an actual PR.
