Home/End keys navigate history instead of moving cursor within prompt

[bero]

Description

Parent Issue

Part of #4997 (Keybinds)

Summary

Home and End keys navigate to first/last prompt in history instead of moving the cursor to the beginning/end of the current line.

Current Behavior

• Home → Goes to first prompt in history
• End → Goes to last prompt in history

Expected Behavior

• Home → Move cursor to beginning of current line
• End → Move cursor to end of current line

Standard text editing behavior - these keys should control cursor position, not history navigation.

Suggested options ofr fix

1. Swap: Use Ctrl+Home/Ctrl+End for history, Home/End for cursor
2. Config: Add setting like keybinds.home_end: "cursor" | "history"

Steps to reproduce

1. Start OpenCode TUI (opencode)
2. Send a few prompts to build up history (e.g., "hello", "test", "another prompt")
3. Type a new prompt but don't send it: this is my current prompt
4. Position cursor somewhere in the middle of the text
5. Press Home key
6. Actual: Jumps to first prompt in session history
7. Expected: Cursor moves to beginning of "this is my current prompt" Same issue with End key - jumps to last history item instead of end of current line.
