Match CloudPanel site usernames and correct release documentation

[7heMech]

Summary

Addresses findings from the v1.5.0 release review:

• Instatic site username generation:
  • Preserve hyphens within domain labels (example-blog.com -> example-blog) rather than stripping them.
  • Use tldts (trie-based Public Suffix List parser with native TypeScript definitions) to resolve registrable domains, properly handling private suffixes, multi-level domains, wildcards, and exceptions.
  • Retain subdomains for unlisted or custom TLDs.
• Documentation fixes:
  • Clarify {site} template variable behavior in docs/smtp-relay.md and addons/smtp/app/views.ts (leading www. is removed only when the bare domain is not another site).
  • Update docs/decisions/instatic.md and docs/decisions/platform.md to reflect the updated username generation rules and asset handling.
• CI / Tools:
  • Add .coderabbit.yaml to enable automatic reviews on PRs targeting dev.
• Tests:
  • Added regression test cases covering hyphens and PSL edge cases in tests/test-action-common.test.ts.

Test Plan

• bun run typecheck passes.
• bun run test passes (all 58 test files).
• bun run test:installer passes (all 7 cases).
• Build succeeds.

Summary by CodeRabbit

• Bug Fixes

  • Site-user names are generated more consistently for domains with private suffixes, wildcard rules, exceptions, and hyphenated labels, including .local subdomains.
  • SMTP {site} templates retain www. when the bare domain is configured as a separate site; otherwise, www. is removed only when the remaining domain is valid.

• Documentation

  • Updated guidance on site-user naming rules and SMTP {site} domain behavior.

📝 Walkthrough

Walkthrough

Site-user naming now uses tldts to resolve public suffixes and preserves hyphens in domain labels. Tests and documentation describe the naming rules. SMTP template descriptions, repository review settings, and platform asset documentation are also updated.

Changes

Site-user naming

Layer / File(s)	Summary
Suffix-based site-user naming cli/action-common.ts, package.json, docs/decisions/instatic.md, tests/test-action-common.test.ts	Site-user naming uses tldts with private-domain support and preserves hyphens. Documentation describes suffix handling, fallback rules, name length, and prefixes. Tests cover .local domains, hyphenated labels, and suffix rules.

SMTP template guidance

Layer / File(s)	Summary
The {site} token and www addons/smtp/app/views.ts, docs/smtp-relay.md	The template hint and relay documentation state that {site} removes a leading www. only when the bare domain contains a dot and is not another CloudPanel site.

Platform asset documentation

Layer / File(s)	Summary
Browser asset description docs/decisions/platform.md	The platform documentation describes browser assets as separate .css and .client.js files imported as text.

Review configuration

Layer / File(s)	Summary
Automatic review configuration .coderabbit.yaml	The configuration references the CodeRabbit schema and enables automatic reviews for the dev base branch.

- Line 19: Update the `{site}` descriptions in `TEMPLATE_HINT` and the SMTP
relay documentation to state that a leading `www.` is removed only when the bare
domain contains a dot and is not another CloudPanel site. Apply this wording in
addons/smtp/app/views.ts:19-19 and docs/smtp-relay.md:34-37.
