/**
* In-process check for whether context-usage warnings are disabled in project
* config. Mirrors the exact semantics of the same check inside
* hooks/gsd-context-monitor.js (introduced by #1073): an explicit
* `config.hooks.context_warnings === false` disables them; a missing or
* unparseable .planning/config.json keeps them enabled (the default).
*
* #2697: hoisting this check in-process lets the adapter SKIP the context-monitor
* spawn entirely when the user has opted out, instead of paying a full Node boot
* inside the child only to read the boolean and exit. Missing/unparseable config
* MUST behave identically to the hook (enabled) so the default path is unchanged.
*
* @param {string} cwd project working directory (the plugin's currentCwd)
* @returns {boolean} true when context warnings are explicitly disabled
