comments: ';' sets a comment on the current line (disasm + pseudocode)

Bind ';' (NavMixin, so both code views) to a comment prompt for the line under
the cursor. Resolve the line's address (_cursor_ea in disasm, the /*0xEA*/ marker
in pseudocode), prefill any existing comment (parsed from the rendered '//' text),
and apply via the set_comments tool; an empty value clears it.

After setting, reuse the name-generation invalidation (bump_names) so Hex-Rays is
force_recompiled lazily and the pseudocode/disasm refresh in place at the saved
position -- the new '// comment' shows on the line. Marks the IDB dirty (Ctrl+S).

Pilot checks for the pseudocode round-trip. full suite 63/63.
