Add wildcard support for data source file paths

[davidfowl]

Summary

Adds support for glob patterns in data source file paths, allowing users to match multiple files with a single configuration entry.

Based on PR #44 by @vechiato, with added tests for cross-platform verification.

Changes

• Added _expand_file_pattern() function to handle wildcard patterns (*, ?, [])
• Updated cmd_run(), cmd_discover(), cmd_explain(), and cmd_diag() to process multiple matched files
• Files are processed in sorted order for consistency
• Improved error messages to show pattern matching results
• Updated documentation with wildcard examples in README.md and settings.yaml.example
• Added comprehensive tests for glob pattern functionality

Example Usage

data_sources:
  - name: AMEX
    file: data/amex*.csv      # Matches amex-2024.csv, amex-2025.csv, etc.
    account_type: credit_card
    format: "{date:%m/%d/%Y},{description},{amount}"

Test Plan

• Glob pattern matches multiple files
• Single file path (no wildcards) still works
• No matches shows helpful error message
• Diag command shows matched files
• Files processed in sorted order

Closes #44
