fix: pass __dirname to findAndRequirePackageJson for correct package.json resolution

[pyramation]

Summary

Updates all call sites of findAndRequirePackageJson() to pass __dirname as a required parameter. This fixes a bug where the function was finding the wrong package.json (the helper package's own package.json instead of the caller's).

The root cause was that __dirname inside the helper function pointed to the compiled helper's location (node_modules/find-and-require-package-json/dist/), not the caller's location. This caused errors like:

Plugin [email protected] requires graphile-plugin-connection-filter@^2.0.0 (not found)

Updated packages:

• graphile-many-to-many
• graphile-plugin-connection-filter-postgis
• graphile-plugin-connection-filter
• graphile-postgis
• packages/cli
• packages/pgpm

Also includes dependency version bumps (pg, @types/pg, lru-cache, etc.) and adds find-and-require-package-json@^0.8.0 as a dependency to the affected graphile packages.

Review & Testing Checklist for Human

• Verify all graphile plugins load correctly and report their own version (not find-and-require-package-json's version)
• Test pgpm --version and lql --version commands return correct package versions
• Confirm CI passes for the build and test jobs that were previously failing

Recommended test plan: Run the graphile plugins in a test environment and verify the version checking logic works correctly (e.g., the "requires graphile-build-pg@^4.4.0" dependency check should pass).
