src: add --enable-run-hooks for node --run pre scripts

[anonrig]

Summary

node --run intentionally does not run lifecycle scripts. This adds an
opt-in --enable-run-hooks flag that, together with --run, also runs the
matching pre<script> hook (when present in the package.json "scripts"
object) before the requested script.

• The hook runs first; if it exits non-zero, the run is aborted and the main
  script does not execute.
• Mirroring npm, positional arguments after -- are forwarded to the requested
  script only, not the hook.
• Missing hooks, non-string hook values, and a missing main script are all
  handled without running anything spurious.
• Without the flag, --run never runs hooks — existing behavior is
  unchanged.

Only the pre hook is supported (no post), keeping the feature minimal and
opt-in; the docs' "intentional limitations" note is updated accordingly.

Example

$ node --run build --enable-run-hooks   # runs `prebuild`, then `build`
$ node --run build                      # runs `build` only (unchanged)

Implementation

• New --enable-run-hooks per-process option (src/node_options.{h,cc}).
• task_runner::RunTask takes a run_hooks flag; it resolves pre<command_id>
  up front (copying the command and rewinding the simdjson object so the main
  lookup is untouched), runs it via a ProcessRunner, and aborts on failure.
• src/node.cc passes cli_options->enable_run_hooks through.
• Docs: doc/api/cli.md + doc/node.1.

Test plan

New test/parallel/test-node-run-hooks.js with a cross-platform fixture
(test/fixtures/run-script/hooks/, echo-based so it works on both sh and
cmd.exe), covering:

• hook runs before the script (and in order) with the flag
• hook does not run without the flag
• failing hook aborts the script (exit 1, main output absent)
• failing hook ignored when hooks disabled
• positional args reach the script only, not the hook
• missing hook → script still runs
• non-string hook value is ignored
• existing test-node-run.js / node_run_non_existent.js still pass
• cpplint clean, test-cli-node-print-help passes
• CI (make lint-js / lint-md + full matrix)
