03/04: deep enrichment of loader/exec format and linking/libraries
Sections 03 and 04 augmented to bootcamp quality with targeted
enrichment based on content analysis (not just file size).
03_loader_and_exec_format:
- overlay_system.md: full rewrite — tree architecture diagram,
HUNK_OVERLAY binary format, overlay manager runtime internals,
worked binary example, linker support, modern alternatives
- hunk_relocation.md: full rewrite — visual before/after diagram,
patching algorithm with code, RELOC32SHORT and DREL32 formats,
PC-relative impact comparison table, self-referencing relocs,
error scenarios, Python reloc scanner tool
04_linking_and_libraries:
- library_structure.md: full rewrite — ASCII memory layout diagram,
JMP table encoding (why 6 bytes), MakeLibrary internals with both
function array formats, complete library creation example with
.fd file, checksum verification, lifecycle state diagram
- shared_libraries_runtime.md: full rewrite — OpenLibrary 4-step
resolution path, ramlib disk loader internals, disk search path,
version negotiation table (v33-v47), CloseLibrary/Expunge deep
dive, memory-low sweep, common pitfalls table
- register_conventions.md: full rewrite — FPU register map,
inter-library A6 save/restore pattern, small-data model with
__saveds keyword, varargs/TagItem pattern deep dive,
stack-based wrapper explanation, disassembly identification
Updated indexes:
- 03_loader_and_exec_format/README.md
- 04_linking_and_libraries/README.md
- Root README.md (sections 03 and 04)

exec_os: enrich all stubs to bootcamp-quality reference articles
Complete rewrite of 14 exec_os articles from stubs to comprehensive
deep-dive technical references with architecture diagrams, pitfalls,
and best practices.
New: multitasking.md (scheduler, IPC, memory safety, real-world scenarios)
Enriched: exec_base, tasks_processes, library_system, library_vectors,
interrupts, exceptions_traps, memory_management, message_ports, signals,
semaphores, io_requests, lists_nodes, resident_modules
Updated indexes: 06_exec_os/README.md, root README.md
