fix(config): make endpoints optional and use relative schema path

[AnnatarHe]

Summary

• Add omitempty tag to Endpoints field in config struct for proper optional serialization
• Change YAML schema reference from absolute path to relative ./config-schema.json

Test plan

• Verify config serialization omits empty endpoints field
• Verify new config files reference schema with relative path

Summary of Changes

Hello @AnnatarHe, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the configuration system by making the Endpoints field optional during serialization and by switching the YAML schema reference to a relative path. These changes improve the flexibility of configuration files and ensure better portability across different environments, particularly for IDE autocompletion.

Highlights

• Optional Endpoints: The Endpoints field in the ShellTimeConfig struct now includes omitempty tags for TOML, YAML, and JSON, allowing it to be omitted during serialization if empty.
• Relative Schema Path: The YAML schema reference has been updated from an absolute path to a relative path (./config-schema.json), improving portability and consistency for IDE autocompletion.

Code Review

This pull request makes the Endpoints field optional in the configuration and updates the YAML schema path to be relative. My review focuses on improving path handling for cross-platform compatibility, reducing code duplication, and ensuring consistency between your configuration struct tags and your documentation. I've suggested using filepath.Join for constructing paths, deriving the schema filename dynamically to avoid hardcoding it twice, and correcting an inconsistent TOML tag to match your documentation.

[gemini-code-assist]

To ensure platform-independent path construction, you should use filepath.Join instead of string concatenation with /. This will prevent potential issues on operating systems like Windows that use a different path separator. This follows the repository's general rule for path handling.

You'll need to add "path/filepath" to your imports.

Suggested change

	schemaFile := configDir + "/config-schema.json"
	schemaFile := filepath.Join(configDir, "config-schema.json")

References

1. Use filepath.Join to combine path segments for platform independence, rather than hardcoding path separators.

[gemini-code-assist]

The schema filename config-schema.json is hardcoded here, but it's already used to construct schemaFile on line 48. To avoid this duplication and improve maintainability, you can dynamically get the filename from the schemaFile path using filepath.Base().

This will require importing the path/filepath package.

Suggested change

	schemaHeader := "# yaml-language-server: $schema=./config-schema.json\n"
	schemaHeader := fmt.Sprintf("# yaml-language-server: $schema=./%s\n", filepath.Base(schemaFile))

[gemini-code-assist]

The TOML tag ENDPOINTS is in uppercase, which is inconsistent with the YAML and JSON tags (endpoints). More importantly, it contradicts your own documentation in docs/CONFIG.md (line 308) which uses [[endpoints]] (lowercase). To ensure consistency and align with your documentation, you should use a lowercase tag for TOML as well.

Suggested change

	Endpoints []Endpoint `toml:"ENDPOINTS,omitempty" yaml:"endpoints,omitempty" json:"endpoints,omitempty"`
	Endpoints []Endpoint `toml:"endpoints,omitempty" yaml:"endpoints,omitempty" json:"endpoints,omitempty"`
