[tool] date_to_timestamp (#130)

[Z4kM4rm3l]

• File is in tools/ directory
• File has header comments (# tool, # description, # author, # example)
• File has a run() function that returns a string
• Uses stdlib only (no external dependencies)
• Tested locally with python bitbox.py <tool_name> <args>

Closes #130

Hey! Thanks for the contribution. A couple things before merging:

1. Missing required header comments -- every tool needs these at the top:

   • tool: date_to_timestamp

   • description: Converts a date string (YYYY-MM-DD) to a Unix timestamp

   • author: @Z4kM4rm3l

   • example: date_to_timestamp "2024-06-30" -> "1719705600"

2. The run function signature should use *args to match the project convention, e.g.:
   def run(*args) -> str:
   date_str = args[0]

Once these are fixed, good to go!

Hey! Just a reminder - the following still need to be fixed:

1. Add header comments at the top of the file:
   `python

tool: date_to_timestamp

description: Converts a date string (YYYY-MM-DD) to a Unix timestamp

author: @Z4kM4rm3l

example: date_to_timestamp "2024-06-30" -> "1719705600"

`

2. Fix run() signature to use *args:
   python def run(*args) -> str: date_str = args[0]

3. Fix title to: [tool] date_to_timestamp (remove the ([tool] date_to_timestamp #130))

Once fixed, we can merge!
