Hermes Agent v0.15.0 slashes runtime, expands Kanban

Hot take: this reads less like a feature dump and more like a maturity release, where the team spent real effort paying down architecture debt and shaving latency everywhere that users feel it.

• –The `run_agent.py` refactor is the headline: moving from a monolithic file to modular internals is the kind of change that usually unlocks the next several releases.
• –Performance gains are user-visible, not vanity metrics: faster startup, fewer function calls, and a much faster `session_search` suggest a serious focus on day-to-day usability.
• –Kanban becoming a true multi-agent platform makes Hermes feel closer to an operating system for agent work, not just a chat wrapper.
• –The security work matters: promptware defenses and secret-management simplification are the kind of additions that make adoption less fragile.
• –The new skill bundles and TUI orchestration features point toward a more opinionated workflow layer, which should reduce friction for power users.
