Keyboard reading modified

[zesk1999]

Description

When using the Spy prompt in a terminal, pressing Delete (and other navigation keys) inserted a literal ~ instead of doing the expected action.
This happened because those keys on Linux terminals send a multi-byte sequence like ESC [ 3 ~. Our code read up to the number (which was before not recognized by code) but didn’t consume the final ~, so it got echoed on screen.

Changes introduced in this PR

• properly consumes the final ~ on Linux for these keys and performs the correct action
• adds the matching key codes for Windows so behavior is consistent on both platforms (introduces a small file-scoped helper consume_tilde_if_present())

Linux terminal:

ESC [ 2 ~ → Insert: now cleanly ignored
ESC [ 3 ~ → Delete: delete char at cursor
ESC [ 5 ~ → Page Up: previous command in history
ESC [ 6 ~ → Page Down: next command in history / clear if none
ESC [ H → Home: move cursor to start of line
ESC [ F → End: move cursor to end of line

Windows console:

Insert = 82 (ignored)
Delete = 83
Page Up = 73
Page Down = 81
Home = 71
End = 79
