style: add missing spaces

[Planeshifter]

Description

What is the purpose of this pull request?

Follow-up fixes for commits merged to develop between 2026-08-11 16:39 PT (99b2dea) and 2026-08-12 01:35 PT (6e66cf0).

This pull request:

• blas/ext/base/ndarray/ccopy-within: fix indentation in blas/ext/base/ndarray/ccopy-within's .d.ts @example blocks: the 'dtype' lines are 4-space indented, one space short of the repo convention — same issue already fixed at the namespace level in 7026843, just missed here (from ba1e337). Re-indents the 4 lines to 5 spaces to match scopy-within and sibling packages.
• blas/ext/base/ndarray/zcopy-within: fix zcopy-within types example indentation to 5 spaces; blas/ext/base/ndarray/zcopy-within/docs/types/index.d.ts ('dtype' lines) missed the 5-space convention applied to the namespace declarations in 7026843 (from 6dbb82e). Re-indents all four occurrences to match scopy-within and the rest of the tree.
• stats/base/dists/arcsine/logcdf: fix expected[i] → expected[ i ] in the six lines added by 99b2dea for the arcsine logcdf ULP migration, in test/test.factory.js and test/test.logcdf.js (3 lines each); leaves the untouched unspaced lines alone, matching every other ULP migration in this window.

Validation performed on the 40-commit window:

• Style guide compliance audit (two independent passes) of all hand-written changes against docs/style-guides and established sibling packages (new blas/ext/base/ndarray packages compared against scopy-within, dfill-equal, sfirst-index-equal, dindex-of-falsy, etc.).
• Bug scan (two independent passes) over the introduced code: loop bounds, stride/offset arithmetic, boundary normalization, dtype copy-paste slips, doc example outputs, and test assertions. No bugs found.
• Deliberately excluded: subjective concerns, style preferences not required by the style guide, anything requiring interpretation, and anything whose validation or fix would require touching code outside the window's diff (e.g. pre-existing unspaced array indices on lines not modified in the window).
