What is the purpose of this pull request?

Follow-up fixes for commits merged to develop between 2026-10-31T19:46:31Z (2f24c6d5d) and 2026-11-01T04:57:50Z (7be647734).

This pull request:

ndarray/from-arraybuffer

• Fix RangeError: Invalid typed array length: 1 for empty shapes in lib/node_modules/@stdlib/ndarray/from-arraybuffer/lib/main.js (added in 2f24c6d). When numel( shape ) === 0, minmaxViewBufferIndex returns [0,0], yielding N = 1 and an invalid view for new ArrayBuffer( 0 ) or byteOffset === byteLength; N is now ( numel( shape ) === 0 ) ? 0 : idx[ 1 ] - idx[ 0 ] + 1. This restores vector( new ArrayBuffer( 0 ), 'float64' ), which regressed in af38320 when ndarray/vector/ctor switched to this package.
• Add the missing [@stdlib/array/buffer] link definition in lib/node_modules/@stdlib/ndarray/from-arraybuffer/README.md. The reference is used on lines 25 and 47 but was never defined (2f24c6d). Also remove the unused [@stdlib/ndarray/orders] and [@stdlib/ndarray/index-modes] definitions.

math/base/special/cinv

• Sync the C usage example in math/base/special/cinv/README.md with examples/c/example.c by changing int main() { to int main( void ) {, following the signature change in 2a22c73.

math/base/special/cinvf

• Sync the uniform call in math/base/special/cinvf/README.md with examples/index.js, which 8729960 updated to uniform( 200, -100.0, 100.0, { 'dtype': 'float32' } ). Matches csignumf.

Validation

• Reviewed all 34 first-parent commits in the window. Two agents checked stdlib style-guide compliance against reference packages (blas/ext/base/daxpby, stats/base/dists/beta/pdf, math/base/special/cexp), and two agents scanned for bugs. The two bug scanners found the from-arraybuffer empty-shape bug independently.
• Ran the empty-shape fix with node: arraybuffer2ndarray( 'float64', new ArrayBuffer( 0 ), [ 0 ], [ 1 ], 0, 'row-major' ) and vector( new ArrayBuffer( 16 ), 16, 'float64' ) now return empty arrays. 0-d and negative-stride cases are unchanged.
• Excluded on purpose: anything that needs interpretation, and anything outside the changed lines. That covers the csignum/csignumf C doc wording, a duplicated test title in from-arraybuffer, and "the package" vs "the packages" grammar in the dxpby README.
• Not run: the full test suites. tape is not installed in the review environment.
