feat(getters): add GetFloat64 and GetInt64, fix docs

- Add GetFloat64 and GetInt64 methods to ConfigManager and package-level API
- Fix README precedence: actual order is Set > env > file > default
  (was incorrectly documented as file > env > default)
- Fix GetStringMap return type in API table: map[string]any, not map[string]string
- Bump Go to 1.26.1
- Add tests for all new getters (coverage 94.7% → 95.2%)

-## Migration Guide
-
-### From v0.x to v1.x
-
-#### Breaking Changes
-
-1. **`WriteConfig()` now returns `error`**
-
-   ```go
-   // Before
-   jety.WriteConfig()
-
-   // After
-   if err := jety.WriteConfig(); err != nil {
-       // handle error
-   }
-   // Or if you want to ignore the error:
-   _ = jety.WriteConfig()
-   ```
-
-2. **Go 1.25.5 minimum required**
-
-   Update your Go version or pin to an older jety release.
-
-#### Non-Breaking Improvements
-
-- Getters (`GetBool`, `GetInt`, `GetDuration`) now return zero values instead of panicking on unknown types
-- Added `int64` support in `GetInt`, `GetIntSlice`, and `GetDuration`
-- Improved env var parsing (handles values containing `=`)
