Teknium a0770d0954 fix(cli): flush-left responses + native clipboard /copy for clean copy/paste
Streamed response text carried a 4-space _STREAM_PAD indent and the
final-response Rich Panel used padding=(1, 4), so every line selected
out of the terminal came with leading whitespace. Both now render
flush-left (pad empty, panel padding=(1, 0)); the table-realignment
width budgets were widened to match.

/copy now writes the ORIGINAL message text through native clipboard
tools (pbcopy / PowerShell Set-Clipboard via base64 / wl-copy / xclip /
xsel — same fallback chain as the TUI's writeClipboardText), falling
back to OSC 52 only when no native backend succeeds. This is the
TUI-equivalent answer to soft-wrap mangling: the clipboard gets the raw
text, not the rendered layout.

"""Streamed response lines must be flush-left (no leading indent).
The 4-space ``_STREAM_PAD`` indent made every copied line carry leading
whitespace, so pasting a response out of the terminal produced broken
text. The pad is now empty and the final-response Rich Panel uses zero
horizontal padding for the same reason (July 2026).
