Without this, git on macOS with core.autocrlf=true checks out .sh
files with CRLF. Bash then reads 'CONTAINER_NAME\r' as the variable
name (never set), causing 'unbound variable' with set -u.

Two silent failure modes:
1. lines() drops any output chunk not terminated with \n — a script
that crashes mid-line (or any final output without a newline) was
silently swallowed. Switched to raw 4KB chunk reads which stream
incrementally and capture everything.
2. A non-zero exit with no output (e.g. bash exit 127 'command not
found') left the log completely empty. Now always appends
'[hiy] exit code: N' after the process finishes so there is always
at least one diagnostic line regardless of script output.
Exit code lookup:
exit code: 0 -> success
exit code: 1 -> script hit 'set -e' on a failing command
exit code: 127 -> bash could not find the script or a command in it
exit code: 126 -> script found but not executable (chmod +x missing)
exit code: signal -> process killed by OS signal

When run_build() returned an Err (e.g. spawn failure because the
build script path doesn't resolve) the error was only written to
tracing, leaving the deploy log empty and the user with no clue.
- build_worker now appends the Rust error message to the deploy log
before setting status=failed, so it appears in the UI.
- run_build logs CWD, resolved script path, exists=true/false, build
dir, and env file path before attempting spawn, so there is always
at least one diagnostic line in the log even if spawn itself fails.
- spawn() error is wrapped with the attempted path for clarity.

Two bugs causing 'can't see why deploy failed':
- showLog() called window.location.reload() on the SSE 'done' event,
wiping the log panel before the user could read it.
- For already-finished deploys, SSE would immediately fire 'done' and
reload, showing logs for < 1 second.
Fix:
- showLog() now fetches the deploy via REST first. If done, it renders
the stored log directly (no SSE). If still running, it streams via
SSE and closes without reloading when done.
- Added onerror fallback: re-fetches the log via REST if SSE drops.
- Status badge (green/red) updates inline instead of triggering reload.
- Page now auto-opens the latest deploy log on load so the failure
reason is visible immediately without any clicking.
