Pull request overview

This PR migrates the extension's logging infrastructure from a custom Logger implementation to LogTape, a modern structured logging library. The migration simplifies the codebase by removing custom logging code and adopting a standard logging solution.

Changes:

• Replaced custom Logger class with LogTape's structured logging API
• Updated all logging call sites to use LogTape's template literal syntax and structured properties
• Removed logger parameters from constructors across providers, linters, and managers in favor of local logger initialization

Error logging loses stack trace information. The previous implementation logged both the error message and stack trace separately, which is helpful for debugging. Consider including stack trace in the properties object when err is an Error instance.

Suggested change

	this.logger.error`Exception caught: ${err}`;
	if (err instanceof Error) {
	this.logger.error`Exception caught while executing ctags: ${err.message} ${{ error: err, stack: err.stack, name: err.name }}`;
	}
	else {
	this.logger.error`Exception caught while executing ctags: ${String(err)}`;
	}

Fatal log is issued after the error message variable is created but the variable is never used in the thrown Error. The logging happens but the actual Error thrown uses a redundant string literal instead of errorMessage variable.

Suggested change

	this.logger.fatal("Extension not found", { extensionId: extensionID });
	this.logger.fatal(errorMessage, { extensionId: extensionID });
