chore: prune dangling bin symlinks, point paging at signal-mcp

The install bin loop linked every script under claude-templates/bin but never pruned orphans, so a deleted script left a dangling ~/.local/bin symlink. page-signal hit exactly this: the wrapper was removed 2026-06-12 but its symlink stayed, resolving to a dead target on the daily drivers. I added a prune step that drops symlinks pointing into claude-templates/bin whose target is gone, so any removed script self-cleans on the next install.

I also added a protocols section naming the two paging channels: notify --persist at the machine, and the signal-mcp send_message_to_user tool when away from it. The pager account was never deregistered (only the page-signal script went away), so the live path is the MCP tool, and the section retires the script for good.
