<issue_title>Extract Command Configuration Constants</issue_title>
<issue_description>Parent Issue: #63
Type: 🎯 Quick Win
Impact: 🟢🟢 Medium
Effort: 🔵 Low
Priority: P0

Problem

Hard-coded magic numbers are scattered across command handlers:

// In create/subcommand.rs
let repository_factory = RepositoryFactory::new(Duration::from_secs(30));  // ❌ Magic number
let mut output = UserOutput::new(VerbosityLevel::Normal);                   // ❌ Hard-coded

// In destroy/command.rs
let repository_factory = RepositoryFactory::new(Duration::from_secs(30));  // ❌ Duplicate
let mut output = UserOutput::new(VerbosityLevel::Normal);                   // ❌ Duplicate

Proposed Solution

Create a constants module at src/presentation/commands/constants.rs:

//! Constants for command handlers

use std::time::Duration;
use crate::presentation::user_output::VerbosityLevel;

/// Default timeout for file lock operations in repository
pub const DEFAULT_LOCK_TIMEOUT: Duration = Duration::from_secs(30);

/// Default verbosity level for user output
pub const DEFAULT_VERBOSITY: VerbosityLevel = VerbosityLevel::Normal;

Then use in handlers:

use crate::presentation::commands::constants::{DEFAULT_LOCK_TIMEOUT, DEFAULT_VERBOSITY};

let repository_factory = RepositoryFactory::new(DEFAULT_LOCK_TIMEOUT);
let mut output = UserOutput::new(DEFAULT_VERBOSITY);

Benefits

• ✅ Eliminates duplicate magic numbers
• ✅ Makes configuration explicit and discoverable
• ✅ Easier to adjust behavior without code changes
• ✅ Better documentation for why specific values are used

Implementation Checklist

• Create src/presentation/commands/constants.rs
• Define DEFAULT_LOCK_TIMEOUT constant
• Define DEFAULT_VERBOSITY constant
• Add module documentation
• Update src/presentation/commands/mod.rs to include module
• Replace hard-coded values in create handler
• Replace hard-coded values in destroy handler
• Verify all tests pass
• Run linter and fix any issues

Acceptance Criteria

• Constants module exists with documented constants
• All hard-coded timeout values use DEFAULT_LOCK_TIMEOUT
• All hard-coded verbosity values use DEFAULT_VERBOSITY
• No duplicate magic numbers in command handlers
• All tests pass: cargo test presentation::commands
• Pre-commit checks pass: ./scripts/pre-commit.sh
• Code follows project conventions
