docs(community): add strands-arise plugin — self-evolving tools

[abekek]

Summary

Adds strands-arise to the community plugins section — a Strands plugin that gives agents the ability to create their own tools at runtime.

ARISE (Adaptive Runtime Improvement through Self-Evolution) detects capability gaps from agent failures, synthesizes Python tools via LLM, validates them in a sandbox, and promotes them to the agent's tool registry — automatically.

• Published on PyPI: pip install strands-arise
• One-line integration: Agent(plugins=[ARISEPlugin(failure_threshold=3)])

Changes

• Added src/content/docs/community/plugins/strands-arise.mdx with installation, usage, configuration, and references
• Updated src/config/navigation.yml to include the new page under Community > Plugins

• Relates to #1680 (Autonomous Tool Discovery) — ARISE synthesizes tools from failure patterns rather than discovering existing ones
• Relates to strands-agents/tools#390 (manage_tools) — ARISE automates the create/test/promote flow that manage_tools proposes as manual actions
