Uppercase OpenCode deep-link schemes are rejected

Description

OpenCode rejects otherwise valid deep links when the opencode URI scheme contains uppercase or mixed-case letters. Both open-project and new-session links are affected. URI schemes are case-insensitive under RFC 3986, and the URL parser accepts and normalizes these inputs, but the app performs a case-sensitive startsWith("opencode://") check before parsing.

This means a launcher or integration that emits OPENCODE:// cannot open a project or start a session even though it identifies the same scheme as opencode://. The parser should validate the parsed URL protocol case-insensitively instead of checking the raw prefix.

Steps to reproduce

1. Evaluate parseDeepLink("opencode://open-project?directory=/tmp/demo"); it returns /tmp/demo.
2. Evaluate parseDeepLink("OPENCODE://open-project?directory=/tmp/demo").
3. Observe that the equivalent uppercase link returns undefined.
4. The same rejection occurs for OpenCode://new-session?directory=/tmp/demo.

Expected behavior: scheme casing should not change the parsed project directory or new-session request.
