Add harness support for RovoDev

[newswim]

Summary

Adds Rovo Dev as a supported provider in the Impeccable build system. Rovo Dev is Atlassian's AI developer agent, with several million users across Jira, Confluence, and Bitbucket-connected workflows.

Skills are read from .rovodev/skills/{name}/SKILL.md at the project level (and ~/.rovodev/skills/ for user-level installs). The format is identical to the Agent Skills standard — full YAML frontmatter including user-invocable, argument-hint, allowed-tools, license, compatibility, and metadata are all supported.

Changes

• scripts/lib/utils.js — Added rovo-dev to PROVIDER_PLACEHOLDERS (model: "Rovo Dev", config_file: "AGENTS.md")
• scripts/lib/transformers/providers.js — Added rovo-dev provider config with configDir: ".rovodev" and full frontmatter field support
• scripts/lib/transformers/index.js — Exported transformRovoDev
• HARNESSES.md — Added Rovo Dev to the provider reference table, frontmatter support matrix, and directory structure table

Because the build loop iterates Object.values(PROVIDERS) automatically, no other code changes were needed — Rovo Dev gets unprefixed and i--prefixed variants, ZIP bundle inclusion, and full test coverage out of the box.

Type of change

• Build system / tooling
• Other: New provider support (Rovo Dev)

Checklist

• Source files updated in source/
• bun run build ran successfully
• bun test passes
• Tested with at least one provider (Rovo Dev — verified SKILL.md output, placeholder resolution, and directory structure)
• README / DEVELOP.md updated if needed

---

Note for maintainers: Rovo Dev reads skills from .rovodev/skills/ (project-level) and ~/.rovodev/skills/ (user-level). It supports the full Agent Skills frontmatter spec. Docs: https://rovo.atlassian.com/docs/skills

looks good, thank you for your contribution! Would be cool to have Impeccable be used by Atlassian users (and Atlassian teams!) worldwide :)
