fix: restore math/base/special tests and remove duplicated REPL text

Description

What is the purpose of this pull request?

This pull request:

Follow-up fixes for commits merged to develop between 2026-09-14T16:19:57-07:00 (adb952a) and 2026-09-15T02:37:51-07:00 (c24d71e).

• math/base/special: Fix: 5258215e0 clobbered lib/node_modules/@stdlib/math/base/special/test/test.js when adding tanhf, git recording the new package's lib/index.js as a rename of it and leaving directories.test in package.json pointing at nothing. Restored the test file verbatim from the parent commit.
• fft/base/fftpack/float32/decompose: Fixes a doc bug from a697555: the refactor of fft/base/fftpack/float32/decompose rewrote two description lines in lib/node_modules/@stdlib/fft/base/fftpack/float32/decompose/docs/repl.txt to backtick N but left the original two in place, duplicating the paragraph in the REPL help. Removes the stale pair.

Validation

All 43 commits merged to develop in the review window were audited for style guide compliance (against docs/style-guides and established reference packages) and scanned for bugs (diff-scoped logic, values, and documentation checks; the new tanhf implementation was executed against its Python-generated fixtures in both JS and C, and the new blas/ext/base/glast-index-greater-than-equal examples were hand-evaluated). Only objective, independently re-verified defects were fixed; anything requiring interpretation, judgment calls, or changes outside the window's diff was deliberately excluded. Notably excluded: fft/base/fftpack/float32/rffti still passing Float32Array workspaces to the refactored decompose — behavior is unchanged and a change would fall outside the reviewed diff.
