Tiptap's built-in bold/italic input rules only fire after whitespace,
so **bold** typed after punctuation (an em dash, an open paren, a
colon) never converted, and [text](url) had no input rule at all. A
small extension adds punctuation-tolerant bold/italic rules (using
lookbehinds so the preceding character isn't swallowed by the rule's
range deletion) and a link rule that fires on the closing parenthesis.
Link URLs pass the same validator as navigation links, so javascript:
URLs stay as plain text, and mid-word patterns like 2**3** are left
alone.
