sneak 179af61c68 Format the rewritten documents with prettier

Re-wraps README.md, docs/ARCHITECTURE.md, docs/DATAMODEL.md,
docs/REPOSTRUCTURE.md and the roadmap in docs/TODO.md with `make fmt`,
which now runs prettier on Markdown. Only line wrapping changes; the
words are those that passed review at 4da102c.

Workflow

branch (from main)
do the work in Next Step
delete Next Step from TODO.md
move the top item of Future Steps into Next Step
commit (TODO.md changes in the same commit as the work)
merge to main if the branch is not protected, otherwise open a PR
push

Status

pre-1.0

Next Step

Fix the open bugs on the issue tracker that block the release. Merging next into main is the owner's.

Future Steps

Work planned after 1.0, loosely ordered by priority.

Correctness and operability

Outside security audit. Before 1.0 the encryption and blob-generation code was reviewed. Every bug the review found was fixed. The risks it accepted are listed in Accepted risks. No outside audit has been done. age, zstd and content-defined chunking are mostly off-the-shelf pieces. The code that joins them needs an outside read:
- key handling
- recipient parsing
- manifest trust boundary
- restore-time identity validation
Verify restored content end-to-end in CI. The current integration test does this for a small synthetic snapshot but not at scale. A nightly job against a multi-GB representative snapshot would catch silent regressions in the chunker, packer, or restore planner.

Performance

Parallel blob downloads during restore. A restore downloads one blob at a time now. With a fast S3 endpoint and a multi-core machine, restore speed is bound by the fetch, decryption and decompression of each blob. Running several of those in parallel against the disk cache would close most of the remaining gap. This needs to interact correctly with the locality planner and the sweeper.
Bandwidth limiting (--bwlimit). For both upload and download. It is useful for backing up over a shared link. It is tricky to make work correctly with parallel downloads.
Restart of interrupted restore. Today a restore can be started again, and it then overwrites the partial output. It does not resume from where it stopped, and it does not skip files that are already present. A --resume mode that checks targets before fetching blobs would matter for very large restores.
Daemon mode. A long-running mode that watches for file changes, so that frequent backups, such as hourly ones, skip the full scan. It adds little for the usual backups from cron every 12 to 36 hours. See issue #204.

Usability

Man pages and richer --help examples. Cobra generates basic help. Man pages would be a separate target.
vaultik snapshot diff <a> <b>. Show which files changed between two snapshots, without restoring either.
Status reporting hook for --cron. When a backup fails silently in cron, the user has no idea. A configurable hook on completion, for both success and failure, would close the loop. It could be a webhook, an email or notify-send.

Infrastructure

Schema migrations after 1.0. Migrations are supported, but none are added before 1.0 because there is no installed base yet. After 1.0, each schema change is a new migration, so an existing local index is migrated when vaultik is updated. See docs/DATAMODEL.md.
Storage backend coverage tests. S3, file:// and rclone:// all share the Storer interface, but the rclone path is the least exercised in CI.
