fix: handle paste events in pair and rename inputs

[gitcoder89431]

Problem

Pressing p on the Connect screen opens the pair-by-ID input, but Cmd+V / Ctrl+V to paste a device ID did nothing. Same issue with the rename input (r). You had to type the full ID manually.

Root cause

PasteMsg is a distinct message type in Bubbletea v2 — it never routes through KeyPressMsg. The Update switch only handled tea.KeyPressMsg, so paste events were silently dropped.

Fix

Added a tea.PasteMsg case in Update that appends to pairInput or renameInput when the respective mode is active. Non-printable characters are filtered out (same policy as the key handler).

case tea.PasteMsg:
    text := strings.Map(func(r rune) rune {
        if unicode.IsPrint(r) { return r }
        return -1
    }, msg.Content)
    if c.pairing {
        c.pairInput += text
    } else if c.renaming {
        c.renameInput += text
    }

Testing

• p → paste a full device ID → enter → device added ✓
• r → paste a new name → enter → device renamed ✓
• All existing tests pass
