Version & Release Oddities
Non-standard version formats and tag prefixes that affect parsing, sorting,
and classification. The Go classifier and internal/lexver must handle all
of these.

Extra dots and numeric segments |

Underscores, beta attached → 3.5.0-beta17 |
Channel Detection
- Node.js: odd major = "current" not LTS (v15, v17, v19, v21, v23)
- Go:
go prefix stripped (go1.23.6 → 1.23.6)
- Terraform:
-alpha, -beta, -rc suffixes → beta channel
Directory Symlinks (Aliases)
These are directory-level symlinks. They share all files (including
releases.conf) with their target automatically.
