Add five project-scoped tools (user-level, no admin required):
project_file_read — read with 1-based offset for paging large files
project_file_list — list with sizes + timestamps
file_stat — size, modified time, line count / entry count
file_grep — regex search with context lines, up to 50 matches
file_syntax_check — py_compile (.py) or json.loads (.json)
Also add offset support to existing file_read (system scope).
Rename "Files" tool category to "System Files"; add "Project Files" category.
Project scope restricted to Cortex_and_Inara_dev/ project root.
