docs: add Ollama (local open-source models) support guide

[yennanliu]

Document how to run the InvestSkill frameworks on local models via Ollama — no API key, offline-capable. Adds README-ollama.md covering the paste path and the tool-capable-client path for live data, plus a platform row in README.md and an Ollama column/section in PLATFORM-COMPATIBILITY.md. Docs-only; all framework counts unchanged.

Code Review

This pull request introduces support for running InvestSkill frameworks locally using Ollama, adding a dedicated README-ollama.md guide and updating README.md and PLATFORM-COMPATIBILITY.md to reflect this new platform. The review feedback highlights two inconsistencies in the updated PLATFORM-COMPATIBILITY.md table: the analysis skills count should be updated from 18 to 25, and the offline support status for Claude Code, Cursor, and Gemini CLI should be corrected to show they do not support offline mode, aligning with their detailed sections.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

The row header states 18 Analysis Skills, but the repository has been updated to support 25 skills (as advertised in README.md and README-ollama.md). Please update this row to reflect the correct count of 25 skills.

There is an inconsistency in the Works Offline row. The table marks Claude Code, Cursor, and Gemini CLI as ✅ (fully supported), but their detailed sections below explicitly state that offline mode is not supported (e.g., line 57: ❌ Offline mode (requires marketplace check), line 112: ❌ Offline mode (Cursor requires internet), and line 175: ❌ Offline mode (requires Gemini API)). Please update the table row to accurately reflect offline support for these platforms.
