refactor: Use SessionStart teleport matcher instead of separate hooks

Change approach from separate PreTeleport/PostTeleport hook events to
using SessionStart with a `teleport` matcher. This is cleaner since
teleporting to CLI starts a new session anyway.

SessionStart matchers:
- `*` - All session starts
- `teleport` - Only teleported sessions (web → CLI)
- `fresh` - Only fresh sessions (not teleported)

Removes pre-teleport.sh example since there's no pre-teleport hook.

+**Available matchers for SessionStart:**
+- `*` - All session starts (both fresh and teleported)
+- `teleport` - Only teleported sessions (web → CLI)
+- `fresh` - Only fresh sessions (not teleported)

 **Use for:**
 - Seamless web-to-CLI workflow transitions
 - Automatic dev server startup after teleporting
-- Preserving uncommitted work across teleports
-- Environment setup automation
+- Pulling latest changes and installing dependencies
+- Running project-specific setup scripts
