feat(ipuaro): add git and run tools (v0.9.0)

Git tools:
- GitStatusTool: repository status (branch, staged, modified, untracked)
- GitDiffTool: uncommitted changes with diff output
- GitCommitTool: create commits with confirmation

Run tools:
- CommandSecurity: blacklist/whitelist shell command validation
- RunCommandTool: execute shell commands with security checks
- RunTestsTool: auto-detect and run vitest/jest/mocha/npm test

All 18 planned tools now implemented.
Tests: 1086 (+233), Coverage: 98.08%
