Free-space start alignment
parted reports free space starting at 0,02 MiB (before the GPT
alignment boundary). The collect_free_space awk now rounds the start
up to the next whole MiB (ceiling) and enforces a minimum of 1 MiB,
then recomputes the usable size from the adjusted start. This prevents
parted from being asked to create a partition at 0 MiB, which it
cannot do.
Locale-independent partition creation
The previous `printf 'Yes\n' | parted mkpart` relied on parted
accepting an English answer to its alignment-confirmation prompt.
On a German-locale system parted asks "Ist dies noch akzeptabel?"
and ignores "Yes", causing mkpart to fail. Replaced with `parted -s`
(script/non-interactive mode), consistent with every other parted
call in the script.
Correct new-partition detection on disks with gaps
The old heuristic took the highest partition number after partprobe.
On a disk where existing partitions are numbered 2/3/4, a new
partition in the gap before them receives number 1 — making the
old heuristic point at partition 4 (the existing btrfs volume) and
subsequently run mkfs.btrfs on it. The new awk matches by start
position (OEMDRV_START ± 1 MiB) instead, which is unambiguous
regardless of how numbers are assigned.
Infinite loop on EOF stdin
When the selection while-loop's `read` hits EOF (e.g. stdin exhausted
after sudo consumed a piped password), it returns exit code 1 with an
empty INPUT, which falls through to "Invalid input." and spins
forever. Added `|| { echo; echo "Aborted."; exit 0; }` to all three
read calls in the loop.
install.md: drop stale install_from_repo.sh reference from title;
clarify that REPO_URL/REPO_BRANCH overrides are optional.

Process substitution does not survive sudo, so the script must be
downloaded to a temp file first.
