/**
 * @fileoverview Command scoring algorithm for fuzzy string matching.
 *
 * This module implements a sophisticated fuzzy matching algorithm that scores
 * the relevance of strings against search abbreviations. The algorithm considers
 * various factors including character continuity, word boundaries, case sensitivity,
 * and character transpositions to provide intuitive search results.
 *
 * The scoring system is designed so that a continuous match of characters
 * results in a total score of 1, with various penalties and bonuses applied
 * based on match quality and context.

/**
 * Calculates a fuzzy match score between a target string and a search abbreviation.
 *
 * This function implements a sophisticated scoring algorithm that considers:
 * - Character sequence continuity (higher scores for consecutive matches)
 * - Word boundary awareness (bonuses for matches at word starts)
 * - Case sensitivity (slight preference for exact case matches)
 * - Character transpositions (handling common typing errors)
 * - Skip penalties (closer matches score higher)
 * - Alias support (additional searchable terms)
 *
 * The algorithm is optimized for typical user search behavior, where users
 * often type the first letters of words or use abbreviations that follow
 * natural word boundaries.
 *
 * @returns A numeric score between 0 and 1, where:
 *   - 1.0 = Perfect match
 *   - >0.8 = Excellent match (typically word boundary matches)
 *   - >0.5 = Good match (some word boundaries or close characters)
 *   - >0.1 = Fair match (scattered character matches)
 *   - 0 = No match
 *
 * @example
 * ```typescript
 * // Perfect abbreviation match
 * commandScore("Hello World", "HW") // ~0.9 (high score)
 *
 * // Partial word match
 * commandScore("Hello World", "Hel") // ~0.95 (very high score)
 *
 * // Character jumps within words
 * commandScore("example", "amp") // ~0.17 (lower score)
 *
 * // With aliases for enhanced matching
 * commandScore("HTML", "markup", ["HyperText", "web"]) // Matches "markup" in aliases
 *
 * // Transposition tolerance
 * commandScore("touch", "otuch") // >0 (handles letter swaps)
 * ```
