Implement setting project attributes via project:info

[pjcdawkins]

Projects support an attributes key, which is a map of string pairs.

AI assistance note

I tried to use Cursor for the implementation: it sort of succeeded with guidance but it was very messy, so I rewrote it. GitHub Copilot's review has been useful.

Pull Request Overview

This PR adds support for setting map-style project attributes via dot notation (attributes.key) in the pro:info command.

• Detects property strings containing . to treat them as map updates.
• Retrieves the correct type for map entries (attributes.*) and handles current vs. new values.
• Adjusts the API payload to use a nested array for map updates and adds an end-to-end test for setting an attribute.

• Update or add a docblock above setProperty to document the new map support via dot notation, parameters ($mapName, $mapKey) and expected behavior for nested updates.

• Consider adding an assertion on the verbose output to confirm the expected confirmation message (e.g., Property attributes.foo set to: bar), and a test that existing attributes remain after setting a new one.
