Overview
This PR introduces foundational components for the BitEstates decentralized property registry, delivering secure document management capabilities while enforcing data integrity through robust validation systems.

Key Changes:

Features
Tag Validation Engine

  • valid-tag + validate-tags private functions
  • Enforces 1-32 char tags & 1-10 tag lists

Property Lifecycle Management

  • register-property: Owner-validated document onboarding
  • update-property: Metadata modification with format checks
  • transfer-property: Secure ownership reassignment
  • delete-property: Owner-initiated record removal

Fixes
Correct registration-block timestamping via stacks-block-height

Documentation
Comprehensive README with:

  • System architecture overview
  • Function specifications + usage examples
  • Error code reference table
  • Contribution guidelines

Impact Analysis

  • Data Integrity: Strict validation prevents malformed metadata
  • Security: Ownership checks on all mutations
  • Usability: Clear docs accelerate developer onboarding
  • Auditability: Block-height tracking for all registrations

Reviewer Checklist

  • Validation logic covers edge cases
  • Ownership tests prevent unauthorized access
  • Documentation examples match current behavior
  • Error codes remain consistent across functions

Introduced `valid-tag` and `validate-tags` private functions to enforce property tag format and list validation requirements. These functions ensure that individual tags meet length constraints and that the tag list adheres to size limits while maintaining consistency.

The `valid-tag` function checks if a tag's length is within the allowed range (1-32 characters). The `validate-tags` function validates the entire tag list, ensuring it contains between 1 and 10 tags and that all tags meet the format requirements.

Impact:
- Enhances data integrity by enforcing strict tag format and list size rules.
- Prevents invalid or improperly formatted tags from being added to the registry.
- Improves the robustness of the property metadata validation process.
Added the `register-property` public function to enable users to register new property documents in the decentralized registry. The function includes comprehensive input validation for property titles, document sizes, descriptions, and tags to ensure data integrity.

Key features:
- Validates property title length (1-64 characters).
- Validates document size (greater than 0 and less than 1 billion units).
- Validates property description length (1-128 characters).
- Validates property tags using the `validate-tags` utility function.
- Automatically assigns ownership to the transaction sender (`tx-sender`).
- Sets initial access permissions for the owner.

Impact:
- Provides a robust mechanism for adding property records to the registry.
- Ensures data consistency and compliance with predefined constraints.
- Establishes initial access control for property owners, enhancing security.
Implemented three public functions to enhance property management capabilities in the registry:

1. **`update-property`**: Allows property owners to update the title, size, description, and tags of an existing property. Includes validation for ownership and input parameters to ensure data integrity.
2. **`transfer-property`**: Enables property ownership transfer to another principal. Validates ownership and updates the `owner` field in the registry.
3. **`delete-property`**: Allows property owners to remove a property record from the registry. Ensures ownership verification before deletion.

Impact:
- Improves flexibility for property owners to manage their records.
- Enhances security by enforcing ownership checks for updates, transfers, and deletions.
- Maintains data consistency through strict input validation.
