feat(install): add Nanobot platform support

[chengyongru]

Summary

This adds Nanobot as another supported Agent Skills platform, in the same spirit as OpenClaw and Hermes.

Nanobot discovers skills from ~/.nanobot/workspace/skills/<skill>/SKILL.md, so the installer uses the existing per-skill linking flow instead of linking one bundled folder. The new platform is appended to the existing platform lists to avoid reshuffling the current order.

Linked issue(s)

No separate tracking issue. This is a small, self-contained platform-support PR.

How I tested this

• bash -n install.sh
• bash install.sh --help
• powershell -NoProfile -ExecutionPolicy Bypass -File .\install.ps1 -Help
• git diff --check
• pnpm lint
• pnpm --filter @understand-anything/core test
• pnpm test
• Manual smoke test

Versioning

• Version bumped in all five manifests
• N/A — internal/docs-only change

Bumped 2.7.6 to 2.7.7 in the five manifests listed in CLAUDE.md.

Hi @chengyongru , sounds good, love HKUDS's work personally. Did you run the analysis on some actual codebase with nanobot yourself?

Hi @Lum1104 💖

I tried Understand-anything in my real workflow (PR review/refactor etc.). Understand-anything works very well with nanobot's longtask mechanism. Here are some screenshots. Really loving it.

Merged it~

@Lum1104 💖 If any compatibility issues between Understand-Anything and nanobot, feel free to @ me. I'd be happy to submit a fix PR.
