`" \nfix it\r"` still pasted a blank first line, because the leading strip
only matched `\n`. /^\s*\n/ drops everything up to the last leading line
break, mirroring the trimEnd() at the other end, and the first real line
keeps its indentation. The test row fails with the old pattern.

"\nfix it\r" pasted an empty first line. Leading line breaks are now
dropped like trailing ones. Document what useMux does with a line feed,
and that a pane without bracketed paste receives each pasted line break
as CR, so a multi-line write without \r runs every line but the last
there, where the old line-stripping typed the joined text and ran nothing.

TmuxManager.sendInput() removed every `\n` before the text reached tmux, so a
multi-line prompt sent with `useMux` (or a multi-line respawn prompt) arrived as
one line with its lines run together: `"echo A\necho B\r"` ran `echo Aecho B`.
The text half of a submit has gone in as one bracketed paste
(buildPasteTextCommands) since the Codex paste-burst fix, and inside the paste
markers Claude Code and Codex insert a pasted line break into the composer
instead of submitting. So the `\n` is now kept (`\r\n` loses only its `\r`) and
the existing paste carries the lines; the Enter stays a separate tmux call.
Multi-line text without an Enter is pasted too rather than typed with
`send-keys -l`, where every line break would reach the pane as a key.
Single-line input is unchanged.
The test-mode gate moves from the top of sendInput() into inputRunner(), as
readPaneRows() does, so a test subclass can record the commands sendInput()
would run instead of pinning the branch shapes on the source.
SubmitVerifier still compares the composer's last glyph line with the prompt
minus its newlines, so it does not reliably recognise a multi-line paste and
may not re-press an Enter that Claude Code ignored. `agent send` and the TUI
therefore keep refusing or joining multi-line input; the docs that described
the stripping now describe the paste and that limit.

Claude Code's and Codex's selection dialogs ignore a bracketed paste, so
after the previous commit a pasted `3` + Enter confirmed the highlighted
option instead of option 3. sendInput() now types a single character with
`send-keys -l` as master did (submitsAsKeys()). One character cannot form
the burst Codex reads as a paste, so the Codex fix is unaffected.
The trailing-`;` escape moves into escapeTmuxTrailingSemicolon() and now
also covers every `send-keys -l` call in sendInput() and
sendInputToPane(); tmux 3.5a types `x;` for `send-keys -l 'x\;'`.
Docs: the @fileoverview lines and orchestrator-loop-architecture.md still
described `send-keys -l`; CLAUDE.md, architecture-invariants.md and
cron-guide.md name the single-character exception.

sendInput() typed the text of a text+Enter pair with `send-keys -l` and
sent Enter 50 ms later. Codex detects an unmarked paste from a fast
character burst and folds an Enter inside that window into the paste as a
newline, so the prompt stays in the composer unsubmitted. Measured with
codex-cli 0.162.1 in a throwaway tmux pane: 1505 chars stuck 3/3 as
`[Pasted Content 1506 chars]`, a 98-char line stuck 1/4. SubmitVerifier
re-presses Enter for the short case, but it cannot match the long one: the
composer shows the placeholder instead of the prompt's head.
The text now goes in via set-buffer + `paste-buffer -p -d` (markers only
when the pane requested bracketed paste), followed by the separate Enter as
before. Same pane, same texts: 4/4 and 3/3 submitted. Each send gets its
own named buffer; a paste that fails (pane or server gone) deletes it,
since tmux never trims named buffers on its own.
Also escapes a trailing `;` in the text, which tmux treats as a command
separator (`send-keys -l 'x;'` typed `x`, a lone `;` typed nothing).
sendInputToPane() has no callers in src/ and is left as it was.
