Scripts live 2 levels deep in source (scripts/bash/, scripts/powershell/) but are packaged into .documentation/scripts/bash/ and .documentation/scripts/powershell/ — 3 levels deep. The hardcoded ../.. resolved to .documentation/ instead of the repo root, causing CONSTITUTION_EXISTS to always be false and all derived paths to be wrong.

Changes

• scripts/powershell/get-pr-context.ps1 — replace Resolve-Path "$scriptPath\..\.." with git rev-parse --show-toplevel, falling back to $scriptPath\..\..\..\; $repoRoot is now a plain string so three $repoRoot.Path references are dropped to $repoRoot
• scripts/bash/get-pr-context.sh — replace cd "$SCRIPT_DIR/../.." with git rev-parse --show-toplevel, falling back to cd "$SCRIPT_DIR/../../.."

Both scripts now match the pattern already used by common.ps1/common.sh (Get-RepoRoot / get_repo_root), which all other scripts depend on correctly.

# Before
$repoRoot = (Resolve-Path "$scriptPath\..\..")   # lands at .documentation/

# After
$gitRoot = try { git rev-parse --show-toplevel 2>$null } catch { $null }
if ($LASTEXITCODE -eq 0 -and $gitRoot) {
    $repoRoot = $gitRoot.Trim()
} else {
    $repoRoot = (Resolve-Path "$scriptPath\..\..\..\").Path   # correct 3-level fallback
}
