<#
.SYNOPSIS
    List unresolved review threads on a pull request (all reviewers).

.DESCRIPTION
    Fetches review threads via GraphQL (paginated) and prints every
    thread that is still `isResolved: false`. Threads from all reviewers
    (Copilot, humans, other bots) are included; the triage step decides
    what to do with each.

    Each thread's `comments(first:1)` is the originating review comment
    — that's where `path`, `line`, and `body` come from. Reply chains
    on the same thread are intentionally not surfaced here; this script
    is the input to triage, not to reading conversation history.

.PARAMETER Owner
    Optional; auto-resolved from `gh repo view`.

.PARAMETER Repo
    Optional; auto-resolved from `gh repo view`.
.PARAMETER PrNumber                  The pull request number.

.EXAMPLE
    pwsh 03-list-open-threads.ps1 -PrNumber 122

.PARAMETER MaxBodyLength
    Cap the `Body` column at this many characters (default 500; pass 0 to
    disable). Long Copilot comments otherwise dominate stdout and slow
    triage; truncated bodies are suffixed with `…`.
