feat: nix build enabled

nix build
will put binary into nix store, and symlink to ./result
running with
./result/bin/auth-pocketbase-attempt serve --dir=./pb_data

if i understood migrations correctly, when using as a framework
migrations will be generated as go files, and will be packaged into the binary

+*** well, especially with go.mod dependencies i'd need to use buildGoModule
+but
+[efim@chunky:~/Documents/personal/go-learning/auth-pocketbase-attempt]$ ./result/bin/auth-pocketbase-attempt serve
+2023/10/07 04:05:56 mkdir result/bin/pb_data: read-only file system

+
+so, if i call executable from somewhere, it looks for pb_data in current directory
+
+but then for some reason
+[efim@chunky:~/Documents/personal/go-learning/auth-pocketbase-attempt]$ ./result/bin/auth-pocketbase-attempt serve
+2023/10/08 06:37:19 mkdir result/bin/pb_data: read-only file system
+
+here it tries to init pb_data near the binary
+
+this works:
+[efim@chunky:~/Documents/personal/go-learning/auth-pocketbase-attempt]$ ./result/bin/auth-pocketbase-attempt serve --dir=./pb_data
+
+*** oh, i don't need to specify location of migrations.
+because they are static. and should be just present in the nix store
+
+and --dir is already built in. nice
+
+well, i don't see any pb_migrations in my project directory even though,
+i'm creating and updating the table
+maybe it's all in pb_data now?
+
+if now - i'll need to add something like
+#+begin_src nix
+            postBuild = ''
+              cp pb_migration $out/bin/pb_migration
+            '';
+#+end_src
+
+*** so, if using as framework migrations are not automatically enabled?
+https://github.com/pocketbase/pocketbase/discussions/2218
+
+https://pocketbase.io/docs/go-migrations/#enable-go-migrations
+The prebuilt executable enables the migrate command by default, but when you are extending PocketBase with Go you have to enable it manually
+*** now `nix build` produces the binary capable to run the site
+and
+#+begin_src bash
+./result/bin/auth-pocketbase-attempt serve --dir=./pb_data
+#+end_src
+is what i need for it to pick up pb_data from work directory, cool

+if i understood correctly, when i enable migration generation
+i would be able to modify locally run instance via admin interface,
+go files with migration would be generated, i'll have to import them somewhere in my main module, and then after building/packaging when i run `serve` on production the migrations would run on the production data
