Add repository-level Claude settings configuration (#69)

## Summary

Introduces a shared `.claude/settings.json` configuration file to
establish repository-level settings for Claude AI assistant integration.
This ensures consistent behavior and permissions across all contributors
using Claude within this project.

## Key Accomplishments

- **Added `.claude/settings.json`**: Defines repository-wide Claude
configuration that applies to all developers working in this codebase
- **Standardized AI assistant behavior**: Establishes a shared baseline
of permissions and settings to ensure predictable and safe interactions
with the codebase
- **Improved developer experience**: Contributors using Claude will
automatically inherit these project-specific settings without needing
manual configuration

## Details

The new settings file configures repository-level preferences for
Claude's operation within this project. This is a shared configuration
(checked into version control) that complements any user-level settings,
providing project-specific defaults and guardrails.

## Breaking Changes

None. This is a purely additive change that introduces a new
configuration file. Existing workflows are unaffected.

## Testing Notes

- Verify that Claude respects the settings defined in
`.claude/settings.json` when operating within this repository
- Confirm that the settings file is properly recognized and loaded by
Claude tooling
- Ensure no conflicts arise between repository-level settings and
individual user-level configurations

## Infrastructure Considerations

- This configuration file follows the `.claude/` directory convention
for project-level AI assistant settings
- The file is committed to version control intentionally so that all
team members share the same configuration baseline
- Future updates to Claude's capabilities or permission model may
require revisiting these settings
