feat: support running commands from subdirectories in monorepo

[Zih0]

Summary

Add support for running CLI commands from subdirectories in a monorepo by resolving process.cwd() behavior differences across package managers.

Problem

When running docflow commands from a subdirectory (e.g., packages/web), path calculations failed because process.cwd() behaves differently across package managers:

Package Manager	process.cwd()	INIT_CWD
npm/pnpm	Repo root	Invocation directory
yarn	Invocation directory	Invocation directory

This inconsistency caused incorrect relative path calculations for workspace packages.

Solution

getWorkingDirectory()
Returns INIT_CWD ?? process.cwd() to get consistent invocation directory across all package managers.

Package manager

• NpmPackageManager: Calculate path.relative(cwd, pkgPath) from absolute path field
• YarnPackageManager: Find repo root via yarn.lock location, then calculate relative paths

Command updates
Replace process.cwd() with getWorkingDirectory() in commands.

Result

Users can now run docflow build, docflow check, and docflow generate from any subdirectory in a monorepo, regardless of which package manager they use.

Minor: What do you think about using the find-up library here? It's more robust and battle-tested than maintaining our own implementation.

I've applied review.

Missing EOL here. Might be worth checking our formatter settings.

[Zih0]

This repository doesn't have a formatter (prettier or biome) configured.

I'll create a separate PR to apply formatting across the codebase.

LGTM except for two minor comments. Feel free to merge if you don't think they're relevant.
