Stellar Agent v0.3.0

0.3.0

• Added fee-stat-aware transaction building with base, low, medium, high, and p95 fee strategies, including session caching and base-fee fallback behavior.
• Added guarded Testnet pay batch support for bundling multiple payments into one transaction with per-payment policy checks and aggregate spend-limit evaluation.
• Tightened signed-XDR submission so ambiguous Horizon submit responses are confirmed by transaction lookup before reporting success.
• Added cache inspect and cache clear commands plus global --no-cache support for long-running agent sessions.
• Expanded CLI help smoke coverage, docs-linked error hints, and agent integration docs for faster setup and troubleshooting.
• Updated GitHub Actions workflow actions to Node 24-runtime majors while keeping the project test runtime on Node 22.
