Add the chunk upload and progress APIs from PLAN.md. PUT
/api/uploads/{id}/chunks/{index} now accepts raw octet-stream bodies, validates
unknown upload ids, out-of-range chunk indexes, and exact chunk lengths, then
writes through a temporary .part.tmp path before renaming the completed chunk
into place. Re-uploading an already-complete chunk is idempotent when the
existing file length matches the expected length.
GET /api/uploads/{id} now reports server-authoritative progress by scanning the
chunk directory and only counting chunk files whose lengths match metadata. The
router also raises Axum's request body limit to 64 MiB so the planned 16 MiB
chunks can reach the handler, matching the nginx deployment guidance.
Document the chunk storage responsibility and extend the reusable test checklist
with the new progress and validation coverage.

Add the first upload API endpoint from PLAN.md. POST /api/uploads now
validates the requested file name, generates a server-owned upload id, creates
the staging and complete directory layout, and writes durable meta.json before
returning chunk scheduling details to the browser.
Keep filesystem layout knowledge in storage.rs so later chunk upload and
completion work can reuse the same boundary. API handlers translate storage
errors into JSON HTTP responses without leaking layout details into the router.
Document the new modules and UPL_DATA_DIR configuration, and extend TESTS.md
with the automated creation coverage.

Introduce the first PLAN.md milestone: replace the hello-world binary with
an Axum server that binds to localhost by default, exposes a health endpoint,
and serves the static browser UI from the repository's static directory. The
router is available through the library crate so integration tests can exercise
server behavior without opening a network listener.
Add a justfile for routine validation and document the initial project shape,
configuration knobs, and reusable test checklist. The rustfmt config now uses
only stable options so the new formatting recipe runs without nightly warnings.
The upload API and resumable chunk behavior are intentionally left for later
milestones; the UI currently handles file selection only.
