* fix(pty): deliver multiline agent-launch prompts via bracketed paste
Multiline agent-launch prompts (claude/codex/opencode argv injection) were
mangled when Orca typed the startup command into the interactive shell. The
command is single-quoted, but its literal embedded newlines survive quoting;
bash readline / zsh zle read every raw LF as accept-line (Enter), so the first
newline submits an unterminated single-quoted command, drops the shell into PS2
(>) continuation, and the rest executes piecemeal — backticks/$ evaluate, quotes
go unbalanced, and the agent never receives the intact prompt. Short single-line
prompts worked because they have no embedded newline.
Fix: when a startup command contains a newline, wrap the payload in
bracketed-paste markers (ESC[200~ … ESC[201~) before the trailing submit CR/LF
so the line editor inserts the multiline text literally and only the trailing
byte submits it. The single-line fast path is unchanged. Gated on the target
line editor having bracketed-paste mode active (Orca-wrapped bash/zsh) so shells
without it never echo the markers as garbage; Orca's bash rc wrappers now force
`enable-bracketed-paste on` (zsh has it on by default).
Applied consistently across every startup-command delivery path:
- src/main/providers/local-pty-shell-ready.ts (in-process / degraded local)
- src/main/daemon/terminal-host.ts (daemon host — primary local)
- src/relay/pty-handler.ts (SSH relay, remote host)
- src/renderer/src/lib/ssh-background-startup-delivery.ts (hidden SSH tab)
All share src/shared/startup-command-submission.ts. Windows cmd.exe and other
shells keep the current CR submit path (no regression); PSReadLine/POSIX
bash/zsh get the fix.
* Fix multiline detection for CRLF-terminated startup commands
Strip the entire CRLF terminator (or lone CR/LF) from startup commands
before checking if the body contains newline characters.
Previously, slicing off only the last character of a CRLF-terminated
command left a trailing CR in the body. This caused a single-line
command to be incorrectly categorized as multiline and wrapped in
bracketed paste.
