* chore: move to new ESLint config format

ESLint is providing a new config format (typically called flat config).
The old config format will be deprecated in ESLint 9.0 (currently in
rc), and will be removed in ESLint 10. This commit migrate from the old
 config format at .eslintrc.js to the new flat config one at
 eslint.config.js.

In addition, 3 packages were added:

- @types/eslint: A dev dependency used to provide ESLint rules code
suggestion.
This dependency is used to provide linting through jsdoc for `styleRule`
 function. It has a very weak consumption (only 1 function relies on
 it), but it is a small types package. The old config file also relies
 on it (but does not install it as a npm package).

- globals: A dev dependency used to configure ESLint global linting
environment.
It is consumed by various other package, and already present on the
path. Although, some package depend on a very old version of globals
(babel), and with how terrible npm symlinking is, ESLint would import
version 11.x.x, with a tragic yet funny bug that will break ESLint.

- typescript-eslint: A dev dependency that provide first class
Typescript integration with ESLint.
It provides a convenient config function fully typed to create ESLint
flat config array. Additionally, provide the recommended
Typescript/ESLint settings that can be conveniently extended.

This commit also deleted 2 other dependencies:

- @typescript-eslint/eslint-plugin
- @typescript-eslint/parser

Both these two packages are no longer needed to be explicitly declared
as typescript-eslint already import them. And it will make better
decision on which version of them it should depend on.

chore: ESM support

package.json is changed to declare module (ESM), practically mark the
project as an ESM first class. Additionally, using ESM module to
configure Playwright and ESLint.

* chore: change npm lint script

With the new config file format, ESLint no longer accepts --ext flag,
as the new configuration file is capable of that already.

* fix: __dirname on Node 18

- @stylistic/indent:
This rule is recommended to be disabled by ESLint
author because it aren't very aware about lesser than traditional
Typescript elements. In fact, it pops up in the most random places,
some places hand-formatted, some conflict with formatter(s).

Trivia: it conflicts with both prettier and dprint on indentation.
Considering even dprint doesn't have the neccesary configuration to
amend it, actually pretty(er) amazing.

Alternative: disable the rule inline where it is less than amusing for
the rule to kick in. Disabling a styling rule confuses the reader about
unneccesary diretives, so it isn't a strong option.

- @typescript-eslint/no-unused-vars:
Configure the rule to ignore the _XXX pattern for unused arguments and
variables. This is the TypeScript "noUnusedLocals" configuration
behavior. In fact, _ is considered unnamed/throwaway in a majority of
programming languages.

The front API for the new serialization (for structuredClone) is in
src/lib/optimizer/new/format.

It relies on user supplied serialization and deserialization method to
safely serialize/deserialize instances to JSON. By default, if a class
is not configured to implement Serializable<SerializedFormat, Class>,
Object.create(clazz.prototype) will be used for deserialization.

Revisited classes that will be serialized to integrate the new API.

test/refactor: Jingliu optimization test suite

- Added 2 new optimizer tests for Jingliu, one with 133 SPD limit.
- Added unit tests for the new serialization API.
- Grouped the test into proper test suites.

- Added 2 new optimizer tests for Jingliu, one with 133 SPD limit.
- Added unit tests for the new serialization API.
- Grouped the test into proper test suites.

test: move unit test into its own folder (unit-tests).

feat: add the progress update feature, allowing main thread to listen
for partial optimization completion event.

test: added a test that for progress update.

Previously, the calculation logic (which set effects are active,...etc)
is in iteration/index.ts, which make it hard to calculate a single shot
damage with a specified formula and build.

feat: proof of concept implementation of tingyun, dhil and jingliu

3 characters were re implemented with the new optimization system to
probe for feedback.

Reference implementation for Boothill, Black Swan and Topaz.

fix: stacking step for dhil

Should we rewrite it in Rust?
