docs: fix description and return annotations in new ndarray/base/*-like packages

[Planeshifter]

Description

What is the purpose of this pull request?

Follow-up fixes for commits merged to develop between 2026-05-14 18:46 UTC and 2026-05-15 11:20 UTC (commit range b517ce1..f0ed784, 21 commits reviewed). A post-merge review found two newly added packages carrying documentation defects:

• ndarray/base/falses-like: Fix documentation defects introduced in 2dcfa84 — removed Markdown backticks from the description field in package.json (plain text, per convention in ndarray/base/falses and ndarray/base/nulls-like) and corrected the @returns tag in docs/types/index.d.ts from filled ndarray to `false`-filled array to match the value-qualified convention used across sibling packages.
• ndarray/base/trues-like: Fix documentation defects introduced in 2e5a8c9 — removed Markdown backticks from the description field in package.json (plain-text convention, per ndarray/base/trues and ndarray/base/nulls-like) and corrected the @returns tag in docs/types/index.d.ts from filled ndarray to `true`-filled array to match the value-qualified convention used by zeros-like and nulls-like.

Each package's fixes are committed separately.

Scope. All 21 commits merged to develop (first-parent) between 2026-05-14 18:46 UTC and 2026-05-15 11:20 UTC — a union diff of ~4900 insertions across 125 files: new ndarray/base/{falses,trues,nulls}-like packages, ndarray/base/{falses,trues} generic-dtype support, ndarray/base/{reverse,to-reversed} test/benchmark updates, ml/base/kmeans/algorithm-resolve-{str,enum}, the blas/base/dgemm resolveStr refactor, and bot-generated docs/declaration commits.

Validation performed.

• Style-guide compliance: changed code audited against docs/style-guides and compared against established reference packages (ndarray/base/zeros-like, ndarray/base/nans-like, blas/base/transpose-operation-resolve-str, and the parent ndarray/base/{falses,trues} packages). Only the two package.json / .d.ts deviations above were confirmed.
• Bug & security scan: the diff was scanned for incorrect logic, copy-paste errors, and security issues. No high-signal bugs were found — the falses-like/trues-like/nulls-like fill values, the kmeans resolvers, and the dgemm resolveStr refactor are all correct.

Deliberately excluded. Subjective suggestions, style preferences not mandated by the guide, "might-be" problems, and anything requiring changes outside the reviewed diff window to validate. Bot-generated namespace/TOC/declaration commits were noted but not modified.
