zzzhizhi 177dd36e23 fix(hooks): allow tmux-wrapped dev server commands (#321)
* fix(hooks): fix shell splitter redirection/escape bugs, extract shared module

- Fix single & incorrectly splitting redirection operators (&>, >&, 2>&1)
- Fix escaped quotes (\", \') not being handled inside quoted strings
- Extract splitShellSegments into shared scripts/lib/shell-split.js
  to eliminate duplication between hooks.json, before-shell-execution.js,
  and pre-bash-dev-server-block.js
- Add comprehensive tests for shell splitting edge cases

* fix(hooks): handle backslash escapes outside quotes in shell splitter

Escaped operators like \&& and \; outside quotes were still being
treated as separators. Add escape handling for unquoted context.
