Fix registry path validator parsing and satisfy mission protocol gate

[Copilot]

marketplace-integrity failed in Validate registry paths exist because .github/scripts/validate-registry-paths.sh had a Bash parse error (unexpected end of file). The failure came from invalid error-handling syntax around the Python heredoc block.

• Root cause

  • The script combined a heredoc with || { ... } in a form Bash could not parse, so execution stopped before any path checks ran.

• Change made

  • Replaced the invalid construct with a valid if ! ... <<'PYEOF' ... then ... fi wrapper around the Python extractor command.
  • Kept script behavior and output semantics unchanged; only parsing/control-flow structure was corrected.

• Code shape (before/after)

  # before (parse error)
  python3 - "$REGISTRY" >"$TMPFILE" <<'PYEOF' || {
    echo "ERROR: Path extractor (python3) failed..." >&2
    exit 1
  }
  ...
  PYEOF
  
  # after (valid)
  if ! python3 - "$REGISTRY" >"$TMPFILE" <<'PYEOF'
  ...
  PYEOF
  then
    echo "ERROR: Path extractor (python3) failed..." >&2
    exit 1
  fi

Additionally, the PR now includes a mission protocol artifact to satisfy the non-trivial PR gate in the same workflow:

• Added .github/MISSIONS/copilot-to-copilot-fix-marketplace-integrity-gate-2026-05-13.md with the required mission keys.
• Updated mission context and validation steps so validate-mission-protocol.sh passes for this branch.

Pull request overview

This PR fixes a Bash parsing error in .github/scripts/validate-registry-paths.sh that caused the marketplace-integrity workflow’s “Validate registry paths exist” step to fail before running any checks. The change rewrites the Python heredoc invocation to use a Bash-valid if ! ... <<'PYEOF' ... then ... fi error-handling structure.

Changes:

• Replaced an invalid heredoc || { ... } construct with a valid if ! ... heredoc ... then ... fi wrapper.
• Preserved the script’s behavior/output while ensuring the script parses and can execute path validation.

Implemented the mission protocol gate fix in commit 1bf7455 by adding a valid mission file at .github/MISSIONS/copilot-to-copilot-fix-marketplace-integrity-gate-2026-05-13.md (with all required keys) and validating it against the PR range; the mission protocol check now passes locally.
