Feat: Enhance rule set

[xpirad]

This pull request introduces enhancement to the AssemblyScript ESLint plugin, including two new rules (no-concat-string and specify-type) to improve code quality and performance, updating the sample ESLint configuration, and other minor adjustments. Below is a breakdown of specific changes in this PR.

New Rules Added:

• no-concat-string Rule:
  • Prohibits string concatenation inside loops to avoid performance issues caused by repeated memory allocation and garbage collection. Suggests alternatives like array.join() or string builders. [1] [2]
• specify-type Rule:
  • Enforces explicit type annotations for variable declarations, especially for numeric types, to enhance WebAssembly type safety and performance. [1] [2]

Plugin Updates:

• Rule Integration:
  • Added no-concat-string and specify-type to the plugin's rule set in plugins/asPlugin.ts.
• Test Coverage:
  • Included tests for the new rules in tests/asPlugin.test.ts.

Sample ESLint Configuration:

• Enhanced Configuration:
  • Updated sample_config/sample_eslint.config.mjs to use consistent double quotes and added new rules such as no-implicit-globals, curly, and @typescript-eslint/no-restricted-types to enforce stricter coding practices. [1] [2]

Minor Adjustments:

• File Cleanup:
  • Removed sample_config/** from .prettierignore to ensure proper formatting of sample configuration files.
• Updated Word List:
  • Added sonarjs to the typechecker in cspell/project-words.txt.
