bin/dev --verbose option documented but not implemented

[AbanoubGhadban]

Bug Description

The bin/dev --verbose option is documented in the help text but is not actually implemented in the OptionParser, causing an error when users try to use it.

Steps to Reproduce

cd spec/dummy
./bin/dev --verbose

Expected Behavior

The command should run with verbose output for pack generation, showing the full bundle exec rake react_on_rails:generate_packs output.

Actual Behavior

/lib/react_on_rails/dev/server_manager.rb:162:in `run_from_command_line': 
invalid option: --verbose (OptionParser::InvalidOption)

Root Cause Analysis

The issue was introduced when the run_from_command_line method was refactored in commit ce30d89 (#1790). The verbose parameter support was added earlier in commit 3878825, but when the OptionParser was created in the later commit, the --verbose/-v flag parsing was not included.

Current State

1. ✅ Help text documents --verbose, -v option (line 218 in lib/react_on_rails/dev/server_manager.rb)
2. ✅ start() method accepts verbose: parameter (line 11)
3. ✅ Verbose parameter is threaded through to PackGenerator.generate() (lines 419, 426)
4. ✅ PackGenerator correctly implements verbose output behavior
5. ❌ OptionParser in run_from_command_line() does NOT parse --verbose or -v (lines 147-162)
6. ❌ All calls to start() hardcode verbose: false (lines 170, 172, 178)

Fix Required

In lib/react_on_rails/dev/server_manager.rb, add to the OptionParser (around line 157):

opts.on("-v", "--verbose", "Enable verbose output for pack generation") do
  options[:verbose] = true
end

Then update the start() calls to use the option:

# Line 170
start(:production_like, nil, verbose: options[:verbose], route: options[:route], rails_env: options[:rails_env])
# Line 172
start(:static, "Procfile.dev-static-assets", verbose: options[:verbose], route: options[:route])
# Line 178
start(:development, "Procfile.dev", verbose: options[:verbose], route: options[:route])

And initialize the options hash with the verbose key (line 145):

options = { route: nil, rails_env: nil, verbose: false }

Impact

• Users cannot enable verbose pack generation output
• Documentation misleads users about available options
• Debugging pack generation issues is harder than intended
