fix: restore plugin header Version line clobbered in rebase conflict resolution

QA P1 from 2026-06-12-6ed639d verdict: the docblock Version field was replaced
by stray define() lines during the CTO rebase of this branch over v0.19.4,
leaving get_plugin_data() with no version. Header restored; the real constants
at the Plugin Constants block are untouched.

-## [0.20.2] - 2026-06-13
-
-### Removed
-- **`scripts/deploy.sh`** — belonged to the retired zip/REST deploy receiver flow
-  (`/wp-json/prautoblogger-deploy/v1/*`); the live pipeline is the shared rsync workflow
-  (`peptiderepo/peptide-e2e/.github/workflows/deploy-app.yml@main`).
-- **`.distignore`** — used by `scripts/deploy.sh` to build the production zip; no longer
-  consumed by any workflow (the shared rsync pipeline uses hardcoded `--exclude` flags).
-
-
-## [0.20.1] - 2026-06-12
-
-### Fixed
-- **Restore three bootstrap constants deleted by the v0.19.0 constants-block regression**
-  (`PRAUTOBLOGGER_DEFAULT_RUN_CEILING_USD` 0.50, `PRAUTOBLOGGER_DEFAULT_REQUEST_JSON_RETENTION_DAYS` 14,
-  `PRAUTOBLOGGER_DEFAULT_REASONING_MAX_TOKENS` 2048 — verbatim v0.18.3 values). PR #156 (v0.19.0)
-  dropped them from `prautoblogger.php`; the gap was latent because `tests/bootstrap.php` defines
-  its own fallbacks (CI green) and no exercised v0.19.x runtime path read them (prod reasoning
-  disabled). v0.20.0's activator defaults + run-state ceiling read them on the admin
-  migration path -> fatal 500 on all plugin admin pages immediately after the v0.20.0 deploy
-  (2026-06-12; front-of-site unaffected; hot-patched on prod within minutes, this commit makes
-  it canonical). Follow-up owed: CI guard asserting every referenced PRAUTOBLOGGER_* constant
-  is production-defined or defined()-guarded (maintenance thread).
