chore(release): bump version to v1.6.3

Next.js standalone bakes absolute build-time paths (outputFileTracingRoot,
appDir, turbopack root) into server.js and required-server-files.json.
When installed via npm on a different machine, these paths don't exist,
causing ENOENT errors. The prepublish script now replaces build-machine
absolute paths with '.' (relative) so they resolve correctly wherever
the package is installed.

+## [1.6.3] — 2026-02-28
+
+### 🐛 Bug Fixes
+
+- **Database data preservation on upgrade** — Previously, upgrading from older versions (e.g. v1.2.0 → v1.6.x) could cause data loss by renaming the existing database when a legacy `schema_migrations` table was detected. Now checks for actual data before deciding to reset ([#146](https://github.com/diegosouzapw/OmniRoute/issues/146))
+- **Hardcoded build-machine paths in npm package** — Next.js standalone output baked absolute paths from the build machine into `server.js` and `required-server-files.json`. On other machines these paths don't exist, causing `ENOENT` errors. The prepublish script now sanitizes all build paths to relative ([#147](https://github.com/diegosouzapw/OmniRoute/issues/147))
