docs: mark v0.2 items done and move YAML-driven rules to v0.3

#3 JSON output, #2 more aliases and #4 multi-sheet workbooks are merged. #1
(YAML-driven rules) moved to the v0.3 milestone as a rule-engine refactor that
must preserve exact finding-type parity. No version bump; release is a separate step.

-1. **JSON output** ([#3](https://github.com/migmcc/quality-docs-validator/issues/3)) — first PR; a
-   machine-readable report alongside Markdown (Markdown stays the default).
-2. **More PFMEA / Control Plan column aliases**
-   ([#2](https://github.com/migmcc/quality-docs-validator/issues/2)) — broaden real-template coverage.

-   optional sheet selection.
-4. **YAML-driven rules** ([#1](https://github.com/migmcc/quality-docs-validator/issues/1)) —
-   *stretch / optional*; a rule-engine refactor, deferred to v0.3 if scope grows.
