fix: rename MSWEBA_GLOBAL_CONFIG_DIR to WEBWRIGHT_CONFIG_DIR

[nuthalapativarun]

Summary

• Env var MSWEBA_GLOBAL_CONFIG_DIR renamed to WEBWRIGHT_CONFIG_DIR in src/webwright/__init__.py
• Migration: if you set MSWEBA_GLOBAL_CONFIG_DIR in your shell profile, rename it to WEBWRIGHT_CONFIG_DIR

Why

PR #4 renamed the project from mini-swe-webagent to Webwright but left the legacy MSWEBA_ prefix in the config dir env var. The old name is confusing and inconsistent with the project's current identity.

Changes

• src/webwright/__init__.py: env var lookup updated from MSWEBA_GLOBAL_CONFIG_DIR to WEBWRIGHT_CONFIG_DIR
