Anthropic blocks specific lowercase tool names (bash, read, write, edit)
when using OAuth tokens. This fix:
1. Renames blocked tools to capitalized versions (Bash, Read, Write, Edit)
in pi-tools.ts via renameBlockedToolsForOAuth()
2. Passes all tools as customTools in splitSdkTools() to bypass
pi-coding-agent's built-in tool filtering, which expects lowercase names
The capitalized names work with both OAuth tokens and regular API keys.
