* fix(terminal): prevent Windows multiline paste submission
* fix(terminal): normalize chunked forced-paste line endings
Windows multiline pastes over TERMINAL_PASTE_DIRECT_MAX_BYTES (64 KiB)
take the chunked plan and stream plainText straight to the PTY, skipping
wrapTerminalBracketedPasteText — so raw CRLF/LF still reached ConPTY and
Codex treated the LF as submit, the exact bug the direct path just fixed.
Wire the plan's newlinePolicy field: forced bracketed plans get
'terminal-cr' and the chunk iterator normalizes the full text before
chunking (a per-chunk pass could split a CRLF across a boundary and leak
the LF half). Non-forced chunked pastes keep their documented
preserve-newlines behavior, so macOS/Linux bytes are unchanged.
* fix(terminal): normalize programmatic paste newlines
* test(e2e): harden Windows Codex paste spec per review
Poll for the idle composer placeholder as a positive ready signal (the
negative boot-state check alone can pass on an empty screen), and grow
the large-paste payload so it stays above the 64 KiB direct-max after
newline normalization, keeping the chunked lane covered even if
planning ever measures post-normalization bytes.
