Subject: [PATCH] feat(console): right-click "Copy value" for hashes/addresses
 under the cursor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Right-clicking the output now offers "Copy <value>" when a long alphanumeric token
(txid/blockhash/address, >=16 chars) is under the cursor — resolved via screenToTextPos.
Uses right-click so it never conflicts with the left-drag text selection.
