feat(cli): report executed prisma binary path in --version output

[Yumihariii]

Summary

prisma --version only prints the version string, so when a project runs a hoisted or global prisma you cannot tell which installation is actually executing. This makes the "Output path of current Prisma in -v" request from #7771 impossible to diagnose.

This PR makes the CLI report the absolute path of the executed prisma binary in the version output:

• human output now includes a Path: <absolute path> line (mirroring how yarn shows the resolved binary path);
• json output (--format json) adds a path field alongside version in the result envelope.

Implementation

The --version command is settled by @prisma/cli-engine's settleVersion. I patched that package via pnpm.patchedDependencies to resolve and print the executed binary path from process.argv[1] (resolved through symlinks with realpathOr). The existing --version --format json contract is unchanged — the new path field is additive.

Verification

• node dist/bin.mjs --version → 8.0.0-rc.14 + Path: /…/cli/dist/bin.mjs
• node dist/bin.mjs --version --format json → { "version": "8.0.0-rc.14", "path": "/…/cli/dist/bin.mjs" }
• pnpm vitest run test/version.test.ts → 1 passed

Closes #7771.

Summary by CodeRabbit

• New Features
  • Version output now includes the resolved path of the current executable when available. In human-readable output, the path appears after the version; in JSON output, it is provided as a path field.
  • When the executable path is unavailable, the version is still displayed and the path is omitted from both output formats. This keeps version information available even when no executable path can be determined.

Review details

Systems and components

• observed — package.json (service) was modified; 1 changed file maps to changed impact.
• observed — patches (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in package.json: Added a patchedDependencies entry mapping @prisma/cli-engine to its patch file in the root pnpm configuration.
• observed — Modified behavior in patches/@prisma__cli-engine.patch: settleVersion now obtains the current executable path and includes it in human-readable and JSON version output when available. The new currentBinPath helper returns undefined if process.argv[1] is absent; otherwise, it resolves that entry with realpathOr.

@janpio this is still waiting on a human review — it's mergeable and CodeRabbit found nothing actionable. It's a small, backward-compatible change (adds a Path:/path line to the -v output). Would appreciate a look when you get a chance. Happy to adjust anything.
