Restores benchmark linting behavior lost during the flat-config migration.

Description

What is the purpose of this pull request?

This pull request:

• disables stdlib/jsdoc-private-annotation, stdlib/jsdoc-doctest, and stdlib/no-unnecessary-nested-functions for benchmark JavaScript files.
• enables stdlib/no-bench-string-concat for benchmark descriptions.
• restores the four overrides from the legacy benchmark configuration at commit f6df0741b98.

Without the stdlib/jsdoc-doctest override, linting initializes the rule and evaluates the entire file in a VM. This can start the benchmark harness during CLI linting or editor integration, even before processing any JSDoc examples. Restoring the override prevents that execution.

Related Issues

Does this pull request have any related issues?

This pull request has the following related issues:

• build: switch Makefiles and pre-commit to flat config (gh54 part VII) #10973: migration to flat configuration omitted the benchmark overrides.

What carried over from the reference(s)?

• All four benchmark rule overrides and their original severity levels.

What differed, or what did you have to work out yourself?

• Applied the overrides in the existing flat-config benchmark entry and verified the editor-style lintText() execution behavior, including nested benchmark paths.

No.

Other

Any other information relevant to this pull request? This may include screenshots, references, and/or implementation notes.

Validation:

• Reproduced top-level benchmark execution on the unmodified configuration using ESLint.lintText() with a harmless temporary-file marker.
• Verified benchmark and nested benchmark paths no longer execute that code after restoring the overrides.
• Verified source-file doctest execution remains enabled.
• Verified benchmark-description concatenation is reported and format() is accepted by stdlib/no-bench-string-concat.
• Linted the modified configuration and a representative array/fixed-endian-factory benchmark: zero errors; one existing warning on the configuration's path import.
• git diff --check, normal pre-commit checks, and the pre-push dependency license check passed.
