feat(sql): support for SQLite pragma and encryption pragmas

[HuakunShen]

resolve #7

• Introduced libsqlite3-sys dependency for SQLite support.
• Updated the load method to accept optional pragmas for database connections.
• Enhanced the JavaScript API to demonstrate loading databases with encryption keys and custom pragmas.
• Added VSCode settings for Rust analyzer to enable SQLite feature, to facilitate development.
• Updated Rust code to handle SQLite options and pragmas in the database connection logic.

Now sqlite encryption can be enabled like this.

const db = await Database.load("sqlite:encrypted.db", {
  sqlite: { pragmas: { "key": "encryption_key" } }
});

I already tested on Mac, further testing needed on Windows and Linux.

Preload doesn't support pragma yet, because that will introduce breaking APIs here

plugins-workspace/plugins/sql/src/lib.rs

Line 55 in 43f0f95

preload: Vec<String>,

If we have to support pragma in preload, then maybe something like this?

{
  "plugins": {
    "sql": {
      "preload": ["sqlite:mydatabase.db"],
      "sqlite_options": {
        "sqlite:mydatabase.db": {
          "pragmas": {
            "journal_mode": "WAL",
            "foreign_keys": "ON"
          }
        }
      }
    }
  }
}

I realized one problem, there are two load commands now, one for sqlite one for others. So the current implementation doesn't support multiple features. Either sqlite only or turn off sqlite feature.
Will need a more robust design.

Problem fixed, the latest version supports connecting to sqlite, mysql and postgres at the same time

No one is reviewing this PR.

In the meanwhile, if anyone wants to try this, you can set dependency to my branch in Cargo.toml.
And for JS dependency, you may want to clone my branch and link to it with pnpm/npm/bun link.

+1 on this! I am also waiting to move from my custom implementation to fully adapting to this plugin. Thanks for the PR!

I was also using my custom implementation with cipher using rusqlite.
While I made this PR, it will be a lot of work to migrate from my implementation to this.
And I want to at least wait til this PR get merged to migrate.

BTW I also figured out how to use drizzle to work with this sql plugin and also rusqlite.
Working with sqlite in Tauri now feels like in Electron.
