v1.5.2 — /orca skill-reference fix

Fixed

• /orca command pointed at a skill that no longer exists. The command template told the agent to lean on the orca-browser skill — renamed to orca-automation in v1.5.0. Both references in commands/orca.md corrected so the shipped command resolves to the right skill.

Docs-only patch; no code/API changes. Published as orca-playwright-bridge@1.5.2.
