## QA Audit Fixes
This PR addresses issues found during the 1.0/MVP QA audit.
### Changes
1. **TODO.md: Mark AVIF encoding as done** — AVIF encoding is fully implemented via govips in `processor.go` but was still listed as a TODO item.
2. **scripts/manual-test.sh: Fix form field names** — The manual test script was using wrong field names:
- Login form: was sending `password=...`, should be `key=...` (matching the HTML form's `name="key"`)
- Generator form: was sending `source_url`, `fit_mode` — should be `url`, `fit` (matching the handler's `r.FormValue()` calls)
- This means **the manual test script never actually worked** — login always failed silently because the `key` field was empty.

Uses github.com/gen2brain/webp - a CGO-free library that uses WASM via
wazero runtime for encoding. WebP decoding was already supported.
- Add gen2brain/webp dependency for encoding
- Implement WebP encoding in processor.go
- Add FormatWebP to SupportedOutputFormats
- Re-enable WebP option in generator form dropdown
- Mark WebP encoding as complete in TODO.md
- check: default target, runs fmt-check, lint, and test
- fmt-check: verifies code is properly formatted
- fmt: formats code with gofmt
- lint: runs golangci-lint
- test: runs go test
- build: builds pixad binary with version info
- clean: removes build artifacts
