The line-range patching interface was fragile (models drift on line
numbers), and both tools were redundant with execute_code + standard
shell utilities (cat, grep, sed, ed, ssam). Drop the file server
entirely; update agent configs, system prompt, and documentation.

Move the system prompt from an inline Go string to prompts/SYSTEM_PROMPT.md,
loaded at runtime from ~/.config/ollie/prompts/ via text/template. The prompt
is now editable without recompilation and focuses on behavioral guidance
rather than token-saving directives.
- Remove systemPromptBase constant and token-efficiency instructions
- Add DefaultPromptsDir() for prompt directory discovery
- Load and render SYSTEM_PROMPT.md with {{.WorkDir}}, {{.Platform}}, etc.
- Update mkfile to install prompts/ to ~/.config/ollie/prompts/
