Added full Unicode character support to the TUI's multiline input dialog.
Previously, only ASCII characters (32-126) were captured when typing notes.
Changes:
- Added UTF-8 multibyte character handling to _multiline_input_dialog()
- Properly collects and decodes 2/3/4-byte UTF-8 sequences
- Added explicit UTF-8 encoding to all file I/O operations
- Added ensure_ascii=False to JSON serialization for proper Unicode preservation
This fix allows users to enter umlauts (ä, ö, ü), accented characters
(é, à, ñ), and other Unicode characters in notes, case names, and all
other text input fields.
Tested with German umlauts, Asian characters, Cyrillic, and special chars.
Critical Fixes:
- Fixed IOC extraction order: URLs now checked before domains to prevent duplicates
- Fixed overlapping IOC highlights with overlap detection
- Fixed IPv4 pattern to validate octets (0-255) preventing invalid IPs like 999.999.999.999
- Fixed IPv6 pattern to support compressed format (::)
- Fixed hash extraction order: SHA256 -> SHA1 -> MD5 to prevent misclassification
High Priority Fixes:
- Added 10s timeout to all GPG subprocess calls to prevent hangs
- Fixed indentation inconsistency in storage.py:253
Performance Improvements:
- Removed 8 time.sleep(0.1) calls from demo case creation (800ms faster startup)
Robustness Improvements:
- Added error handling to export_markdown() for IOError/OSError/PermissionError
- Implemented atomic writes for state file (set_active)
- Implemented atomic writes for settings file (set_setting)
All changes tested and verified with unit tests.
- Move all project files from `trace/` subdirectory to the repository root
- Rename directory structure from `fnote` to `trace`
- Update package references and imports (fnote -> trace)
- Update application branding and storage paths (~/.trace)
- Update build script and documentation
- Ensure __pycache__ is ignored
