chore: clean-up

[Planeshifter]

Description

What is the purpose of this pull request?

Follow-up fixes for commits merged to develop between ebbf2de9 (2026-08-08 06:00 PT) and 9bd464a4 (2026-08-09 05:04 PT).

This pull request:

• number/int64/base/identity
  • Fixes %ld → PRId64 in lib/node_modules/@stdlib/number/int64/base/identity/examples/c/example.c (introduced in 5a6af33): int64_t is long long on LLP64/32-bit, so the mismatched conversion specifier is UB and trips -Wformat. Brings it in line with every other C example that prints 64-bit ints.
  • In commit 5a6af33, the C "Examples" section in lib/node_modules/@stdlib/number/int64/base/identity/README.md prints int64_t values with %ld, mirroring the non-portable format specifier fixed in examples/c/example.c. Updates the README snippet to include inttypes.h and use PRId64 so it doesn't hand LLP64/32-bit users undefined behavior when they copy it.
• ml/base/sgd/params/struct-factory
  • lib/node_modules/@stdlib/ml/base/sgd/params/struct-factory/README.md#L65 has a stray extra colon in the l1 bullet under penaltyParams (**l1**: :), introduced in 9bd464a. Drops the duplicate so it matches every other bullet and the l1 entry in docs/types/index.d.ts.

Validation. All 30 commits merged to develop in the window were reviewed for (1) stdlib style-guide compliance (compared against established sibling packages, e.g. dtril, sfill-equal, ztril, dcopy-within, cexp) and (2) objective bugs in the introduced code (loop/stride arithmetic, complex real/imag handling, int64 word handling, JS↔C implementation parity, README/repl.txt example outputs recomputed by hand, affected test suites executed). Only objective, independently re-verified issues are included; the fixed printf pattern was compile-checked with -Wall -Wformat -Werror.

Deliberately excluded: anything subjective or requiring interpretation, deliberate authorial choices (round-nearest-even change in rempio2/rempio2f, per-function ULP tolerances in migrated tests, VLA→malloc benchmark refactor), and one candidate finding (missing __stdlib__ field in blas/ext/base/gtril2triu/package.json) dropped because 49 of 389 sibling packages — including the entire pre-existing gtril/gtriu/gtriu2tril family — omit the field, so the convention is not unambiguous.

Note: this is a draft PR; a maintainer will audit and promote it.
