Added command parser integration

[ZarrarPeshimam]

Description:

This PR improves Jarvis’ command parser to handle flexible phrasing, synonyms, and minor typos. It maps multiple expressions of the same command to the correct intent and triggers the corresponding action.

close issue: #2

Changes Made:

• Updated command_parser to recognize alternative phrasings for common commands (e.g., “time now”, “current time”)
• Added intent-action mapping via handle_user_text()
• Added fuzzy matching for minor misspellings
• Integrated text-based testing for 10+ common commands
• Connected parser to backend.feature for handling actions like YouTube playback, WhatsApp messaging/calls, opening apps, and chatbot responses
• Audio input hook added in hotword() using takecommand() for future testing

Testing:

• All new command variations successfully recognized in text-based testing
• Tested at least 10 common commands including synonyms and minor typos

⚠ Note:

• Audio input testing not performed due to microphone/setup issues
• However, Logic is still fully verified; audio → text conversion workflow is expected to work once audio is enabled

Checklist:

• Text-based commands recognized correctly
• Synonyms and minor typos handled
• Intent mapped to corresponding actions
• Feature integration ready for audio input

The hardcoded threshold value of 70 lacks context and may need adjustment for different use cases. Consider extracting this as a named constant (e.g., FUZZY_MATCH_THRESHOLD = 70) at the module level with a comment explaining the rationale for this value.

Great work @ZarrarPeshimam on this PR! The logic for the flexible command parser, synonym handling, and fuzzy matching looks solid and is a fantastic improvement for Jarvis's natural language capabilities. The integration with backend/feature.py is well-structured.

I see you've already addressed the helpful suggestions from Copilot, which is excellent!

Before merging, we just need to resolve the two failing checks: Black Code Formatter and isort. These are standard checks to maintain consistent code style across the project.

Please run the following commands locally on your branch, commit the changes, and push again:

1. For Black (Code Formatting):

   black .

2. For isort (Import Sorting):

   isort .

Once those checks pass, this PR is good to merge! Thanks for the excellent contribution, and happy Hacktoberfest!
