feat: add 30 interactive components for computer fundamentals section

Added comprehensive interactive demos covering:
- Operating systems (2): OS overview, process/memory/filesystem
- Data encoding (2): data lifecycle, encoding/storage/transmission
- Network basics (5): overview, physical/data-link/transport/application layers
- Data structures (5): overview, linear structures, hash table, tree, selector
- Algorithms (4): overview, recursion, greedy thinking, paradigms
- Programming languages (5): evolution, paradigms, scenarios, comparison, type models
- Compilers (2): analogy, practice demo
- Additional (5): search/sort algorithms, network principles, encoding basics, storage hierarchy, graph structures

Also updated component registration in theme index.js and fixed minor formatting issues in related docs.
