v0.2.70

• hermes --tui and other agent CLIs could leave a stray character on
  screen after a long session: scrolling away cleared it, scrolling back
  brought it back.
• Cause one: xterm 6.0.0 measures emoji with the Unicode 6 width table, where
  a glyph like 🔥 is one cell wide. Every TUI counts it as two, so each cursor
  move after an emoji landed a column off, and the cell it shifted over kept
  the old contents. The terminal now loads the Unicode 11 table, the same one
  VS Code uses.
• Cause two: a multi-byte glyph split across two pty reads reached the
  daemon's parser as bare continuation bytes, one junk cell each, shifting the
  rest of the row. The parser now receives the decoded text.
